I have a Diplomat ADP8221 (which I believe is made by Smeg), it stopped working last week and when I stripped it the main motor was seized. Rather than buy a new one (skinflint!) I stripped it down. The front bearing had seized through water ingress. When I checked the number of the bearing I recognised it as the ones used in skateboard wheels, a 608zz (yes, I’ve just turned 50 and I ride a skateboard!). I got a new bearing off Ebay for £2.15 delivered and thought the job was a good ‘un. The motor is fine now and runs perfectly but another problem has occurred. It runs through approx a third of its programme but sticks on one of the drain positions. I have tried opening the door and introducing some water to the sump and, sure enough, it drains away. I can’t hear the timer ticking and was wondering if it was that sticking. If i leave it to run it eventually stops altogether until I reset the timer manually. I’m guessing there is a safety cut-out? I have tried it several times and each time it sticks at this one position.
My thoughts are either it is a sticking timer or there is a level switch somewhere that isn’t telling it that it has emptied and should move on to the next stage.
I would appreciate any help and, you never know, I may be able to use another bit of a skateboard to fix it?!!!
Re: Diplomat/Smeg ADP8221 Sticking on drain sequence
im no expert but
sounds like a old version with the 4/5 buttons if its smeg /diplomat where u have to old down the button to start it those timers can be screwey, but if your motor had siezed likely chance the stat has clicked ie the cut out stat due to a lack of motion the element has got to hot and the stat that sits in between the element has over heated,
the timer is waiting to be told by the stat that u have reached tempture but if its cut out the element will be getting no power so the machine stay in same postion forever untill stat tells the timer to move on.
cure?
if white stat will have a red reset button below the element underneath
i belive if black stat it may have a reset button or it may not / if not new stat required.
Im guessing if has the push buttons time it be old version black stat with no rest
hope this helpsRe: Diplomat/Smeg ADP8221 Sticking on drain sequence
Thanks for that Karv. The heater is still working though, everything is, the water fills, circulates, heats, even the detergent dispenser opens, its just when it empties it keeps on emptying!
Re: Diplomat/Smeg ADP8221 Sticking on drain sequence
Flood protection activated will run the drain pump indefinitely. If you didn’t replace the leaking pump housing/impellor assembly (why the bearing failed in the first place), the undertray has probably flooded.

Re: Diplomat/Smeg ADP8221 Sticking on drain sequence
Penguin, I can guarantee the undertray hasn’t flooded, mainly because it is still leaning against the wall! I haven’t refitted it yet as I couldn’t make out how it was held in place, I think I must have broken the clips on one side on removal. Would leaving it off cause the same symptoms?
Re: Diplomat/Smeg ADP8221 Sticking on drain sequence
I think you have hit the nail on the head Penguin, tried it with the anti-flood temporarily disabled and it works fine. Maybe faulty switch or a pressure problem in the pipe? I have cleaned out all the plastic unit to the side, that was quite mucky.
