It’s an American style top loader, yes? It has no heater and relies on the hot supply for any sort of warm wash. This means that by now the machine is filthy due to the absence of the ability to do a proper hot wash or a stand-alone service wash.
I have, or the wife has done a stand alone hot wash, this has made no difference and the wife is moaning that its just not washing properly !
Any idears.
The limitation on a hot wash with your machine is your hot water supply. A service wash on a front loader would be carried out at at least 90c; you’ll be limited to 60c at the very most.
The other option would be to get the top off and see about having the inner drum removed to allow everything to be scrubbed clean.
