Hi. My Zanussi DE6744 runs the wash cycle for much longer than usual. The water doesn't get hot. I checked the heater - 25 ohms resistance. I removed the controller, found no damage, replaced it and it worked normally again - a couple of times. Now it's again not getting hot and is again taking too long.
Any ideas welcomed!
Thank you, Dave .
