I have a commercial washer. My questions are, what is the purpose of the thermistor located at end of the water valve? The second question, the washer has a pressure switch. The old one has been replaced now. The new one stays engaged when the machine does not need it. Could you tell me the problem? Thanks
Answer Hello Shug,
The thermistor on the water valve monitors the water temperature for the wash water so the proper water temperature will be injected into the tub for a proper wash result. The pressure switch has to have power to it all the time so it can pass the voltage to start the wash cycle. If the power were discontinued to the pressure switch when the unit filled, it would shut down at that point.
My washer will not switch from hot to cold is this the water inlet valve or temp switch or both?
Answer Hello Dion. In most cases it is the temp switch W10184148. However, the thermistor on the valve can cause the problem as well. Now, this unit will not change based on the selection. It will change when it deems it is needed through the temp switch.
Ok what is a thermistor needed for on the water inlet valve? What does it control?
Answer Hello Trevor. The thermistor controls the water temp coming into the washer.
Washer will fill up when on COLD or Warm setting. When on hot only cold comes in. Thanks for your time.
Answer Alf, if the unit is only filling cold on the hot water setting replace the inlet valve part number 3979346. Thanks!
The washer will not fill with water on the warm setting. It will fill on hot and cold settings.
Answer Hello Bobby. If both the hot and cold are working, it sounds like the temp switch 8564139 may be bad and need to be replaced on the unit.
I had a problem where my machine is not filling with cold water. I replaced the water inlet valve and it worked until I connected the body and put it back in place. Now the machine is still not filling with cold water. What do I check next?
Answer Yvonne, You'll need to check the wiring harness W10121436 and the connections to the fill valve 3979346, especially where the harness passes between the washer top panel and the rear panel. Make sure the harness is inserted through the cut out in the top, and not pinched between the top and the rear panel.
