Washing machine not heating up water

Washing machine not heating up water

Many people believe the washing machine isn’t heating up water when they can't feel any hot water through the door. It is not true, or at least not always. Even the rarest faults happen sometimes, so here’s what you can do if your washing machine fails to heat the water.

No heating error code

All modern washing machines monitor the water temperature, and if it does not rise a certain amount within a pre-defined time, then it should flag a fault. So, if the heater isn't working, then the program should abort and produce an error code.

On an older washing machine the symptoms should be that it carries on washing indefinitely. And even a few modern washing machines can develop faults that cause the washer to stick mid cycle and wash forever without producing an error code even though they are supposed to. If you suspect something like that, call a repairman. It is not a DIY job.

I can’t feel any hot water through the door while washing my laundry

A common belief is that there must be something wrong. Not necessarily, because:

  • The water is only hot inside the washing machine for a small amount of time during a wash
  • Many washing machine doors also have an outer plastic insulating cover so it's sometimes hard to feel any hot water
  • Modern washing machines put so little water in the wash that hardly any warm water splashes on the door glass

All in all, not feeling any hot water through the door doesn’t necessarily mean there is something wrong with the heating, especially when the appliance seems to work fine. The laundry and your washing machine will come out clean thanks to Ariel. So there is no reason to be alarmed too soon!
