Okay, so I’ve run another rinse cycle, and felt the water temperature just after it has taken in the water (stone cold), let it run, and opened it it just as it started to drain, 10 minutes later. There was no difference at all in the water temp, not a trace of warmth, it was stone cold just as it went in.

I tried putting it on the 35C cycle and opening it to check temp after 5 minutes run time and was steaming warm!

So…

1. After 10 minutes Rinse post-filling = stone cold
2. After 5 minutes 35 post-filling = steaming warm (already well over 35C, but not as hot as it gets)

So the element is getting power on the cycles with heat, and not getting power on the rinse cycle.

Does this contribute anything further to the relay/control board theory in your view? Could anything faulty on the control board produce that sequence of events?

How many relays are involved in the NTC/element control circuit? If there is a relay fed by the NTC itself I could believe that would be at fault if it’s on the control board. However, the power stage relay to the element clearly works, unless there is another power control before it that switches both the element AND the NTC?

Kind Regards,

Joseph

Hi Dave,

Thanks very much for your reply! Would a stuck closed element relay adequately explain there correctly being no heating during the Rinse-Only cycle?

I’m not familiar with these machines. Is there another power control on the element circuit that could turn it off for the rinse cycle? Something on the control board is clearly able to not turn the element on for the Rinse cycle.

Kind Regards,

Joseph
