Washing machine won't heat water

1. Problem with the water temperature sensor: The water temperature sensor may be faulty and not accurately detecting the water temperature.
2. Issue with the control board: The control board may be malfunctioning and not properly controlling the water temperature.
3. Clogged inlet valve: The inlet valve may be clogged, which could cause the water to not heat up properly.
4. Faulty heating element: The heating element could be faulty, which could cause the water to not heat up properly.
5. Wiring problem: There may be a loose or broken wire connection between the control board and the heating element or water temperature sensor.

It is recommended to have a professional diagnose the issue, as some of these repairs may require technical skills and specialized tools

If the machine is not progressing past the wash cycle and is stopping at the end of it, there could be a few possible reasons for this. Here are some troubleshooting steps you can try:

1. Check the water inlet valve: If the water inlet valve is faulty or clogged, it can prevent the machine from progressing to the rinse cycle. Check to ensure that the water inlet valve is clean and functioning properly.
2. Check the drain pump: If the drain pump is faulty or clogged, it can cause the machine to stop at the end of the wash cycle. Check to ensure that the drain pump is clean and functioning properly.
3. Check the door latch: If the door latch is not engaging properly, it can prevent the machine from progressing to the rinse cycle. Check to ensure that the door latch is clean and functioning properly.
4. Check the pressure switch: The pressure switch detects the water level in the machine and signals when to advance to the next cycle. If the pressure switch is faulty, it can cause the machine to stop at the end of the wash cycle. Check to ensure that the pressure switch is clean and functioning properly.

If none of these troubleshooting steps work, it may be best to contact a qualified technician to diagnose and repair the issue.

It could be that the machine is trying to heat the water in the drum, but is not able to for some reason. The timer is waiting for the water to reach temperature before advancing. Posssibly a broken heating element. This can happen even on a cold cycle as most machines prefer to heat all soaping water to about 30C regardless of the temperature setting.

Hi

Thanks for using FixYa. If the cycle doesn't complete, then the first thing that should be checked is the Timer and then the heating element. Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it. Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next depends, as follows: On some units, the pause is timed and the unit continues after the allotted time. On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too. Please accept the solution if the issue is resolved or post a comment for further assistance.

Thanks

These machines are designed to have the cold water around 70-75 degrees. If your cold water is colder than that it will automatically mix in hot during the wash cycle to reach that temperature. It all has to do with the optimum temp for proper detergent function.

Bad timer

Make sure you magnet is properly in place its very touchy

Growing up in Europe with front loader washing machines I thought I only had to hook the machine up to the cold water tap and it would heat the water up to the required temperature. However, this model needs to be hooked up to both the hot and the cold water tap in order to function properly. Everything is working fine now that I have done that.

If the cycle doesn't complete, check these:
1. Water-heating cycle
2. Timer

Water-heating cycle
Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

Following up my comment from yesterday, I took the machine apart and discovered that the black rubber cover on the valve that releases the cold water had perished and cracked, and wasn't opening properly.
I tested the hot and cold solenoids and everything checked out ok. Was just the cold valve sticking.
The wash cycle was working because I was using hot/warm water. As the rinse cycle needs cold water to get started, it was not working and the rinse and spin cycles wouldn't complete.
I have swapped the valves over for now (put the working hot one on the cold side and am using cold water only). It's working while I order a replacement...
