The solenoid should lift off, use two flat bladed screwdrivers if possible to avoid bending the brass moulding. It was very common practice to just change this type of solenoid from one valve to another if you didn’t have the correct valve. This type of solenoid was almost universally used on most washers and dishwashers in the 70s/80s/90s.
ln fact looking at that you may have a valve with a plastic core. I have used solenoids, diaphragms, plungers etc from other valves many , many times in the past.don wrote: As for Inonnocenti of which I had not heard of, a quick Google search tells me they were once a Scooter manufacturer!!
Don.
Should have asked me Don, in my youth I had a Lambretta 150Li scooter, the parent company of Lambretta is or was Innocenti. Reg number GBU 622D. 1966 a good year for footy as well. 🙂
It’s very doubtful that the later valve unit would work. It is so long ago now but I think the pressure hose to the later valve was routed from a different part of the machine. The pressure levels would therefore be of a different calibration. The stainless steel solenoid plunger in the valve could be sticking. On later valves the sprung plunger is housed inside a plastic moulding but these earlier valves had a brass like alloy for the solenoid body. Over many years it was possible for a small amount of corrosion to cause the plunger to stick. Also the rubber diaphragm inside the valve deteriorates with age which also leads to valve failure. A very careful strip down of the actual solenoid mechanism to clean everything and inspect the diaphragm would be my next step.
That looks fine and TBH I never had any problems with that part of the valve unit. It was either open circuit solenoids or sticking valves. Usually if you listen closely you can hear the valve buzzing.

Incidentally, my valve is mains 240V.
The whole machine is almost certainly so, electronic controls not common in those days.
If it has a rotary control timer or a bank of large square push buttons and no digital display it is entirely mains voltage.2Tricky wrote:
Update:
Iadom, I’d love a manual if you might have one. Mine’s turned to coal!Unfortunately the only ones I can find are for the later Hotpoint models which were actually Bosch machines made by Hotpoint under license. I gave away all of my hard copy manuals when I retired 3 years ago, still have lots on my hard drive but not that one. 🙁
The other valve or any alternative would be impossible to fit in.
BSH,basically Bosch, Neff, Siemens. I worked for Hotpoint from May 1969 until 1980 when I left to go self employed. These Bosch/Neff dishwashers where made for Hotpoint in the very early 70’s. Models 840, 850, 860 & 870.
Should be BSH not the department store BHS, oops.
BSH Hausgeräte GmbH is the full name of the German parent company.
That is the valve I mentioned. Did occasionally perform intermittently. Always was expensive but that price is staggering.:(
The very first BSH dishwasher made for Hotpoint had a slightly different valve to that one, from memory ( it was a long time ago) the actual solenoid was at a different angle. When Hotpoint decided to go back into selling dishwashers they sent one engineer from each district to Peterborough for a five day course on just this 4 model range. I was the designated dishwasher engineer for all of Manchester North. It was over 6 months before I got my first call out, couldn’t remember how to switch the drained thing on.:)
Not sure but think I might have copies of original manuals, will check later.
Given the door lock problems, the leak and the rather high costs of any motor/control related faults I would sadly advise retirement.:(
If you can find the exact model number you can tell if it has a brush gear motor or not. The very first ISE10 was model number W1406. This has a brush gear motor. The later models starting with W1606 have all got 3 phase motors without brushes.
These are the brushes used in the W1406 machine. D240054 FHP Motor Carbon Brushes (ukwhitegoods.co.uk)
I installed the one and only W1406 on my area in Jan 2008 and my first W1606 on Feb 2008 so yours could well be either.
