Re: Ariston KLS61SUK Not Heating

Thrown in the towel.

Thermostat checked out just fine – going open circuit when brass thread was immersed in hot water.

Door switch was also fine. Could find no trace of hinge activated switches.

Dug deeper into the mechanical timer and cleaned up all the contacts – all appeared to actuate just fine as the dial was moved ’round.
The timer motor may well be at fault – it doesn’t appear to have the ooomph to drive the cams.

Any advice on a replacement?

Thanks, Steve.

I haven’t burrowed into the thermostat or hinge area yet, but did look at the Timer / Control unit, based on responses from similar problems in the forum. This was a little stiff so I freed it up with WD40. The connectors all look in good shape and continuity appears as expected for actuating pumps and heaters. The switchgear for the heater was a little burnt, but no more than I’d expect after 10+ years of daily service.

I cleaned these up with very fine abrasive and reassembled.

Pity it still doesn’t work!

Next stop:
1. Thermostat(s)
2. hinge switches (or would this be the door latch switch – this appears to work correctly).

Thanks for the advice. Will let you know. Rob
