Solenoid Question....

[keymatic]

Dear All,
I need to pick your brains about Solenoid's - recently my Hotpoint 1504 has been filling to high and the other week it nearly flooded, I believe this is down to a faulty "Hot" solenoid as the 2 cold rinse's are fine.
Would i be able to purchase just a regular solenoid ? I can't see that the principal would be any different from that of a modern front loader solenoid.
Can you let me have your thoughts
Cheers
Keith

Hi Keith

I would have thought that you could easily use a universal solenoid with the same fixings and they operate on mains voltage just like the originals. These solenoids are straight through units as some are angled. Can't quite tell how they are fixed on to the panel from my photos though.

Could be worth disconnecting the hoses from both sides of the valve, removing the filter and then energising it (don't touch the terminals) so you can see through the valve. If there is any any scale or crud in it you should be able to clear out before you order a new one. Sometimes you can take them apart but I don't think these ones look serviceable. Alternatively, if your cold water pressure is higher than the hot, you could try switching the supplies over to see if this flushes anything out.

Good luck

I might even have a top loader inlet solenoid valve, grandpa used to take bits off of his old Hotpoint top loaders as thats all he had up until 2001. I was given a load of worktops, filter trays and so on and I think theres an inlet

Will check tomorrow for you

Hi Keith

I'm just overhauling my 1504 as its been sat idle since it rolled off the production line and I've had a closer look at the valves - looks like you can open them up to clean so could be worth a go.

I'll do a full thread on the overhaul when I've finished

Overfilling

It may be worth checking the hose between the sump and the 'level sensing' pressure switch.
I was called out to a machine which 'occasionally' overfilled, gradually doing it more often, until it eventually flooded the woman's kitchen!! The pressure hose had chafed against the drum until a pinhole had developed, causing it to lose pressure and keep 'topping up' until eventually a flood occurred before the end of the wash cycle. Rinses were fine, because they are shorter, and not enough air had escaped from the pipe.

A faulty diaphragm in the switch will give the same effect.

All best
