My Maytag Neptune washer takes longer than usual to complete the cycle.


Hi.


When the washing machine is working, takes an unusually long time to complete the cycle, that is not usually do to a control unit (CCU) fault, but to the fact that one condition needed to follow on the cycle is not met. The CCU may have to wait a longer time, and will not proceed to complete the cycle.

The most obvious thing to check are the water hoses, checking the drain hose and the inlets. If water is not coming with sufficient pressure, or if one of the hoses is blocked or kinked, the cycle time may take much longer than normal.

Other common problems are the pressure switch (SWITCH, PRESSURE), that detects water level, and the thermostat (on self heating models only).
The pressure switch determines when to stop filling and draining. If the pressure switch is faulty, then drain and filling may take much longer or go on forever.


Check also that water valve and dispenser valve are not clogged. (VALVE, WATER) and (DISPENSER VALVE )


On the water valve there may be a thermistor (not all models), check that the thermistor contact is not disconnected (WATER VALVE W' THERMISTOR) , as the thermistor may also be faulty.

What is the purpose of a thermistor


From a dictionary definition, the thermistor is "an electrical resistor whose resistance is greatly reduced by heating, used for measurement and control."

Essentially, what this means in plain english is, the thermistor is a temperature sensing device, designed to govern temperature or protect the machine from an overheat. In a washing machine for instance, as the water heats, the electrical resistance reduces and the controller measures the resistance to guage the temperature of the water, switching the water heater on, of off appropriately, to maintain the temperature the wash is set at.

More typically in a dryer, there will be several thermistors. One in the drum will do exactly as described above, while one or mor different designs of thermistor will be mounted in the heater unit its self. Typically the thermistors in the heater unit will be designed to cut power to the heater if it faults and begins to overheat. These overheat sensors typically come in 3 formats: "Fail ON" device, which allows voltage through at a certain temperature. A self resetting "Fail OFF" device that cuts power at a certain temperature and when the unit cools, restes and restores power. Finally a Fail safe "Fail OFF" device which fails at a higher temperature than the self resetting device. Typically, this last type of failsafe cutout has to be reset by either pushing a reset pin, or inserting a thin pin into the back of the device to reset the position of the convex bi-metal disc that will fail concave. DO NOT BYPASS THESE DEVICES! Typically most machines will finction with them bypassed but you remove ALL safety cutout function for overheat when you do this and create a fire hazzard!!

Steam coming out of the soap tray,seems to be washing extremely hotter than instructed.


A model number would be useful... But, be that as it may, there are several models that have a thermistor mounted along with the heating element. So, if you have one like that, you can change the heating element assembly and that will probably solve the problem. If not, look around for the thermistor that senses the temperature of the water.

Good luck!

Why is my kenmore elite he3 coming up on screen f05


The "F05" error code is indicating a Water Temperature Sensor Error. Does it take long time for the water to get hot when you initially start it? If the water is cold entering the tub when hot water or warm water is selected it possibly could cause the error. It only makes sense because after you cancel the cycle and restart the washer it does OK because the cold water has been purged.

There is a thermistor located on the heating element mounting bracket which is used to monitor the water temperature. The heating element w/thermistor will be located on the lower back portion of the tub. You might find a loose wire connection on the thermistor. You will need to remove the rear panel to access the heater and thermistor. You will need an ohm meter to measure the resistance of the thermistor. See images below for specifications.

NOTE: Disconnect the power cord before removing the rear panel.

If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range, the "F/05" error code will be displayed.

Potential Causes:

Check the Water Temperature Sensor

Check connections to the Water Temperature Sensor

I recommend calling a service technician to diagnose and repair your washer.

Water changes from hot to cold. Valves checked out


Bad thermistor or bad board. Or its just a energy super saver and it will not let you use all that hot water. Did it work before or its been like this since new? New energy star models will only let it just get warm for hot wash, saving energy. warm wash is like 70 deg water.

Thermistor for LG WM2688H


Thanks so much for the tip regarding flipping the machine on its side. I was about do the lengthy process of disassembling the front and I tipped the machine over instead. Lo and behold, there was the problem in plain sight right away -- the wire to the thermistor had simply come off the connector! I restripped the tip of the wire and crimped it back on the connector, problem solved. Didn't even need a new part!

INCREASE THE WATER TEMP AT THE HOUSE WATER HEATER SO YOU WILL HAVE 120 DEGREE WATER COMING INTO THE DISHWASHER. IF THE DISHWASHER IS NEXT TO THE SINK, PURGE THE HOT WATER LINE AT THE SINK UNTIL YOU ACTUALLY GET HOT WATER. THEN, START YOUR DISHWASHER.
