What Water Not Heating means on your Asko washer (asko washer water not heating)
This entry covers a symptom rather than a single Asko error code. The WM75/PMCU platform publishes E6 for a heating error and E1 for a related thermistor failure, but the older display, numbered-LED, analog, and text-label panels the earlier families of this file cover do not list an equivalent heating code at all. So a cold wash on one of those older panels may show no problem indication whatsoever, even though the underlying failure is the same kind of problem.
Symptoms
Line the points below up against your Asko washer to be confident this is the problem you are dealing with and not a similar one. A washer can display a single symptom or several at once, whether they build slowly or appear abruptly after a surge, a spill, or recent installation and testing.
- Laundry and water feel cold at the end of a program that should have been warm or hot
- The cycle time on a heated program may run longer than usual
- No code appears on some panel generations even though heating has failed
- Cold-wash programs are unaffected
Common causes
Several separate problems can leave your Asko washer showing these symptoms, so the causes below are ordered from the most to the least likely. Working through them in that order on your washer tells a quick owner-level check apart from a problem that needs an experienced technician and the right Asko parts.
- Heating element failure — the element has burned out and no longer heats
- Thermistor failure — the sensor is not reporting temperature accurately, so the control thinks the target has been reached
- Heater relay failure — the control is not switching power to the element
- Wiring failure to the element — a damaged connection is interrupting power delivery
Troubleshooting steps you can try
Before you call for service, try each step on your Asko washer in turn and watch how it responds. If a step on the washer takes you near mains wiring, gas, a hot oven cavity, water, or a sealed component, stop and pass it to a qualified technician.
- Check the display for an E6 or E1 code if your machine is a PMCU-platform model.
- Compare a cold-wash program against a heated one to confirm the problem is heating-specific.
- Power-cycle the washer and try the heated program again once.
- Avoid repeating heated cycles if the water stays cold, since that will not fix an element failure.
