Ge washer no warm water

Hi. I was given a used GE washer by a friend. I do not get warm water flowing into the machine. Cold and hot wash are fine. Any thoughts? Thanks

Have you checked the temperature of the water in tub after it’s full in warm water setting? Lid must be closed for warm setting to function properly. This is a safety feature as the washer switches between hot and cold water during warm water fill.

Thanks.

I did fill the machine with the lid closed, and the water in the tub was cold..Only cold is flowing in when on warm setting. I know because i was touching the hot water pipe while filling and it was not hot. However, when on hot setting, the washer switches between hot and cold water, which I gather from your answer is supposed to happen on warm setting, not hot setting. On cold setting, only cold water enters the machine. It seems like the temperature settings are all mixed up. I even unplugged the machine to reset the electronics, but it didn’t help.

According to the parts list for your washer, it does have a temperature sensor. I’m not familiar with this particular model so I can’t say where it is attached but probably plugs into the water dispenser where the water goes into the tub. Look for a two-wire connector on the control board and trace the wires to find exactly where the sensor is located if not at the water dispenser. Check resistance of the probe. Should be 50k ohms at 77°.

The safety feature is so that the incoming water temperature does not change while the lid is open. If you select hot water, the hot water will come in and of course cold water if cold is selected. If warm is selected, only cold comes in if the lid is open. As soon as you close the lid, it will switch between hot and cold to give you warm water based on input from the temp sensor.

Yes, it will switch between hot and cold even when hot is selected because the overall hot temperature is limited to comply with energy saving requirements. I don’t know what the exact temps are for your particular model but probably something like 115-120° for hot and 80-95° for warm but possibly lower since you have a later model.

Thanks.

But wouldn’t the temp sensor be ok since the washer does switch between hot and cold on the hot setting? Is it possibly a problem with the main control board?

Also, please forgive my ignorance, but how do I test the resistance of the temp probe?

To check resistance, unplug it from the control board and use a multimeter across the two wires. The sensor is a thermistor which is a resistor that changes resistance depending on temperature. It should be 50 thousand ohms at 77°F. As the temperature goes up, the resistance goes down and vice versa. It may be a faulty probe, control board or your cold water supply is just too warm. You could unplug the probe from the water inlet and place it in cold water to see if it cycles the hot water on during warm fill. Lid must be closed to do this.

BTW, your not using flood safe hoses or valves are you?

No, not using flood safe hoses or valves. When you say the resistance should be 50k at 77 degrees, what does the 77 degrees refer to, the water temp or the air temp?

Thanks again

The probe temperature, doesn’t matter if it’s in water or not.

Tested the probe and it seems to be ok. What next step do you suggest?
Maybe the control board? Is there anyway to actually test it?

Thanks

Yes, the control board is the only other thing. If you buy it from APP, you can return it if it doesn’t fix the problem. If you get a new board, you must transfer the “model” plug from the old board to the new one. It is a plug on the board that has one or two jumpers on it.
