Presenter
Presentation Notes
Something important to note. Water may splash during the operation of active wash. If there is air in the water pipe or hose after install, water can be supplied so strongly at the moment due to air pressure that it may splash the customer. There is no problem with this Phenomenon. It is normal, and can occur due to air in the pipe.

Frontload Only!
Possible Cause if not maintained - SMELL - Mold
When not in use the door should be left
slightly open to avoid Mold or Smells
What happens if you don’t follow correct installation of the Drain Hose!
For Samsung Washers it is recommended to leave the door open when not using the machine, because not all water is drained mold and smell will develop if the door is closed. Check the user manual for more details
Presenter
Presentation Notes
If the door is closed on the front load, smells will begin to develop. For this reason the front door should be left open slightly when not in use, to avoid smell and mold from forming. This also goes for the detergent drawer. The Drawer should also be left open to avoid odor from developing in the wet environment.
+
Maintenance of the Machine – Cleaning Drum Possible Bad Smell
Possible Cause of - SMELL - Mold - Sud error - ND error
During a Pure Cycle or Self Clean make sure there is no clothing in the tub Self Clean should be run with no detergent or clothing. Use a Washing Machine cleaner if a mold smell is present. Small amount of vinegar or bleach can also be used. When first using Self clean cycle a Suds error or no drain error may occur, this is typically due to the left over detergent in the drum. The Pre cycle should be run again if this occurs.
Self Clean + ( Pure Cycle on Old Machines ) – is used to clean dirt from the drum. Should be used every 40 washes. No detergent or bleach needed.
Presenter
Presentation Notes
Use Self Clean or Pure Cycle to clean the drum. This is more important on front load machines but may also be used on regular basis to clean top loads. When running this option no clothing should be in the machine. The option is run with an empty drum
HOT COLD
Possible cause if installed incorrectly: - Wrong Temperature - Leak
Position of the Hot and Cold hose
+
Presenter
Presentation Notes
Insure the hoses are correctly installed. Hot and Cold are always marked on the back of the machine. Connect the cold to the cold water and hot to the hot water. Make sure there are no leaks. If the Rubber washer was not used the hoses will leak.
Possible cause if not maintained / water quality • NF error • Long Fill time
Washer not filling because of customer Education issue
Check if Valves are ON Position
Clean the Valve Filter regularly in areas with bad water quality
• Hard water and dirt will cause inlet valve to clog. Clean under running water.
• In case of a no fill or slow fill don’t miss t
he obvious check the on and off position of the valves.
+
Presenter
Presentation Notes
Hard water and dirt will cause inlet valve to clog. Clean under running water. In case of a no fill don’t miss the obvious check the on and off position of the valves. Slow fill is normally due to clog or water pressure.
Detergent and Softener type
Avoid cheaper soaps that may include an HE label, but still give your washer over sudsing issues. Stick with the well known name brands
+
Possible Cause if used incorrectly or wrong soap: - Over Suds - Leaking - ND error - Sud error
Presenter
Presentation Notes
HE soap is very important to use, stick with the well known name brands because even HE soaps could cause over sudsing. Also note that using a softener will reduce soap suds.

Presentation Notes
The following will describe how to adjust water temperature and water amount . Press Temp to choose the water temperature, there are 5 temperature settings. Note use heavy duty if Extra hot water is required, Normal mode the Extra Hot will not be as hot, even if extra hot is selected. Press Spin to adjust the load amount, the amount of clothing in the tub. Press Soil Level to adjust the water level inside the tub. Note choose heavy duty wash if heavy water amount is needed.
You can fill the tub with dry, unfolded clothes, but do not overload the tub. No more than ¾ full. Overloading reduces washing efficiency, causes excess wear, and possibly causes creasing or wrinkling of the load. Wash delicate items such as bras hosiery, and other lingerie in the delicates cycle with similar lightweight items. When washing big bulky items or a few smaller items that don’t full the tub completely – a rug, a pillow, stuffed toys, or one or two sweaters, for example add a few towels to improve tumbling and spin performance. Make sure to use the correct setting If washing bedding use the bedding setting • If washing water proof on 2014, use water proof • If washing small load use normal

TESTING THE WATER LEVEL ACCUARACY AND WATER LEVEL SENSOR
DURING A NORMAL WASH CYCLE THE WATER WILL FILL UP TO AROUND 3 INCHES REGARDLESS OF THE SOIL LEVEL THAT IS SELECTED
SUMMARY
Presenter
Presentation Notes
DURING A NORMAL WASH CYCLE THE WATER WILL FILL UP TO AROUND 3 INCHES REGARDLESS OF THE SOIL LEVEL THAT IS SELECTED. YOU CAN SELECT LIGHT, NORMAL OR HEAVY. IT DOSNT MATTER WHAT YOU SELECT ITS STILL GOING TO BE 3 INCHES. THE SOIL LEVEL WILL ADD MORE WATER AT THE END OF A WASH CYCLE BUT THE WASHNIG WATER AMOUNT REMAINS THE SAME. ON A NORMAL SETTING THE WATER LEVEL WILL DISPLAY A VALUE OF AROUND 245 IN THE WATER LEVEL FREQUENCY TEST IN THE SERVICE MODE WHICH IS AN AMOUNT OF WATER IN THE TUB OF 3 INCHES.
TESTING THE WATER LEVEL ACCUARACY AND WATER LEVEL SENSOR
DURING A NORMAL WASH CYCLE THE WATER WILL FILL UP TO AROUND 3 INCHES REGARDLESS OF THE SOIL LEVEL THAT IS SELECTED
SUMMARY
Presenter
Presentation Notes
WHEN HEAVY DUTY IS SELECTED IT WILL ADD A LITTLE MORE WATER THAN NORMAL. THE TUB WILL FILL TO AROUND 3 ½ INCHES INSTEAD OF 3 INCHES LIKE IN NORMAL MODE. Soil level adds more water to the rinse only THE FREQUENCY WILL DROP TO AROUND 243 INSTEAD OF AROUND 245. IT DOES NOT MATTER THE SOIL LEVEL THAT IS SELECTED THIS WILL NOT AFFECT THE WATER LEVEL THAT ENTERS THE TUB. NOTE THAT ON SOME MACHINES THERE WILL BE 2 DIGIT FREQUENCY NUMBERS AND ON SOME THERE WILL BE 3 AND EVEN 4 BUT THEY ALL MEAN THE SAME. PAY ATTENTION TO THE LAST 2 DIGITS. NB: SOME TIPS ON WATER LEVEL FREQUENCY. WHENTESTING THE WATER LEVEL FREQUENCY IN QUICK TEST MODE YOU CAN LEAVE THE WATER LEVEL FREQUENCY SHOWING ON THE DISPLAY WHILE YOU TURN THE WATER VALVES ON AND WATCH THE VALUE CHANGE. YOU CAN ALSO TURN THE DRAIN PUMP ON AND WATCH THE VALUE INCREASE BACK UP TO AN EMPTY TUB VALUE (255 OR 254) IF WATER IS BEING ADDED TO THE TUB AND THE DISPLAYED NUMBER DOESN’T CHANGE THE WATER PRESSURE HOSE MIGHT BE BLOCKED OR DISCONNECTED. ALTERNATIVELY IF THE DIGITS CONTINUE TO FLUCTUATE AND DO NOT STOP AFTER THE WATER HAS STOPPED FILLING (STOPPED BY YOU), THE WATER PRESSURE HOSE MIGHT BE LEAKING. REPLACE THE HOSE IF THIS OCCURS. IF THE WATER LEVEL SENSOR IS DEFECTIVE OR THE CONNECTION IS BAD A 1E ERROR WILL BE DISPLAYED AT STARTUP.

Presenter
Presentation Notes
A good way to check components and harness connections is at the main board. With the power on. If the component is open or the wire harness is bad the reading at the board should give you 120V. If the component is good 0 volts should be your reading. Turn on the washer, check for 120 Volts on CN4 this will check all your valves, your drain pump, clutch right at the board. Place the ground probe on CN1 black wire. Next confirm correct voltage. 0V if component is good and about 120 if the component is defective or wire open. In case of a NG, 1st check wire harness and connection. 2nd check component and replace if needed.

Exhaust air flow, select the rout during install that will provide the straightest and most direct path outdoors. Plan the installation to use the fewest number of elbows and turns. Avoid making 90 degree truns. Remember a dirty vent may cause heating issues and possible fires so advise the customer to clean out regularly.
Venting material is important do not use flexible foil type or plastic.. Do not use exhaust hoods with magnetic latch. Magnetic latches can hold the vent door closed, because the air pressure from the dryer is not sufficient to break the magnetic attraction. Clogged vents , can also be an issue, clogged vents will prevent the clothing from drying properly, make sure the vent is clear of debris and lint build up. Disconnect and show the customer the unit working

FOR EVERY 90 DEGREE ANGLE THE DUCT MAKES SUBTRACT 6 FEET OF ALLOWABLE VENT. DRUYER IS RATED AT A MAXIMUM VENT TO BE NO MORE THAN 30 FEET.
IN THIS EXAMPLE THE DRYER VENT MAKES 4 X 90 DEGREE TURNS. 4 X 6 (FEET) IS 24 FEET. THIS THEN MEANS THAT THE VENT INCLUDING THE 90 DEGREE TURNS SHOULD BE NO LONGER THAN 6 FEET TO THE OUTSIDE VENT 30 FEET MAX. SUBTRACT 24 FEET (4 BENDS @ 6 FEET) 6 FEET REMAINING

Presentation Notes
Make sure the vent is clear of debris and lint build-up. Its possible to remove lint build up from the dryer to the wall as seen in the picture but for anything that is clogged in the vent that you cant access (internal) you may have to advise the customer to get in contact with a dryer vent cleaning company. A simple way to test your suspicions of a clogged vent internally, is to take the vent completely off the dryer. Run the dryer with the vent exposed and determine if it heats and remains heated (with a damp load) in it for a period of time. If it runs probably, the most likely scenario will be a clogged vent. Incidentally clogged vent make up a majority of the dryer calls for a NO HEAT complaint. Put your hand on the vent and check if it gets warm disconnect & show the customer the unit working Remember often the dryer can be pushed back restricting the vent tube that’s why a solid vent tube is always recommended where a flexible hose can collapse in on itself restricting the air flow.
Things to know - Sensor Dry / Time Dry
Sensor Bars
• The sensor dry area will be marked on every machine. When using sensor dry the sensor bars in the front of the dryer will detect the dryness of clothing.
• If a small load is being dried and wet clothing is not touching the sensor bars, the machine will recalculate the remaining time left and speed up or stop the drying process.
• When drying smaller loads choose time dry. Time dry will not use the sensor bars as a reference point when drying clothing. Time dry will dry for the amount of time you select.

Test 2, disconnect the harness and test pink wire pin 4 to orange wire pin 5. approximate value with out laundry is infinity, approximate value with clothing is about 190 ohms. Cycling thermistor 1 Disconnect the harness and test the blue wire pin 3 to red wire pin 6. Approximate 10 K ohms at 77 degrees. Cycling thermistor 2 , disconnect the harness and test yellow wire pin 2 to white wire pin 7 approximate 238 k ohms at 77 degrees.
Models with wrinkle prevent option may create some confusion for the customer. After the unit stops drying it will continue to spin/stop this is normal to prevent clothing from wrinkling the unit will continue to spin and stop for a while. The customer may complain about the unit not stopping or spinning for no reason (Please explain to the customer and check this option)

Blower Housing Component Check
Thermostat 1 NC (<1Ω)
Melf Resistor Thermistor
(10kΩ @ 25oC)
• The resistor thermistor monitors the temperature in the dryer, and feeds the information back to the Main PCB; this in turn controls the function of the heating element
• Thermostat 1 is normally closed and will open up if the temperature in the exhaust fan gets too hot (trapped lint fire)

Noise is one of the biggest issues for redo. Drum imperfections will cause noise and also may cause damage to clothing, don’t forget to look for any damage on the weld. A rattling noise may be caused from an out of balanced bent drum during normal operation. The out of balanced drum may create vibration of the heater duct. After confirming the quality of the drum the following should be done to reduce noise issues. 1. Use needle nose pliers to pull an bend the chassis tabs to create a tighter fit if needed against the heater duct. 2. Use aluminum tape to tape over any vibrating parts on the chassis only, do not add tape to the heater duct or heating elements
