Clothes washing machine doesn't heat water yet reports no errors
Obvious guess is that your ceramic heater element(s) are shot &amp; I couldn't find them online in a quick search, for your model. Take it apart without effecting operation &amp; see if you can confirm by hand or multi-meter. But, it could be a number of things from a loose connection to a dead thermistor. I'd get an Appliance Repairer if you use the heating option regularly.
