Re: Completely stumped ! Help !
I don’t suppose anyone knows how tight the impeller should be screwed in do they ? It’s a left hand thread onto the motor spindle and I’m just wondering if it should be tightened just enough to hold the impeller central in the pump housing, rather than all the way ?
Also the capacitor doesn’t seem to have any terminal identification, so I’m presuming it makes no odds which way around it’s connected ?
Edit: Well, I put it all back together, and it’s made no difference at all.
The motor spins freely and smoothly between my fingers, it’s now got a new impeller and pump housing and a new motor capacitor. The upper bar still refuses to spin.I removed the upper bar from it’s mount and noticed the thin rubber washer around the locking ring was looking rather stretched and distorted, then I noticed the transparent plastic bush that acts as a bearing between the arm itself and the central spigot, was split. I’m guessing a new upper spray bar is needed now. 🙁
Meantime, I’ve managed to get it to rotate slowly by blocking four of the inner jets with self tapping screws. At least it goes round now.

I’ve had everything off ! Top bar, bottom bar, riser pipe, motor, impeller. Everything is clear. Double checked. There are so few components in this it’s got to be the motor or the impeller – I can’t see any other reason why the upper bar wouldn’t spin if it’s not insufficient pressure. The upper bar is plastic and the lower one stainless – the holes in the plastic upper bar can’t enlarge with age can they ?
I’ll order a replacement impeller unit and get a new motor capacitor just in case.
In the back of my mind, I know this is going to turn into one of those ‘DOH !’ moments, where it turns out to be something staring me in the face all along 🙂
Re: Completely stumped ! Help !
The motor spindle turned quite freely between my fingers when the impeller housing was off, and there wasn’t much resistance with it on to be honest. The bearing didn’t feel stiff or rough.
The machine is filling to about 7mm below the overflow drain holes, but I’ll give it a go with a couple of pints more on the next run.
Incidentally, is it usual for the black insulation around the tub to melt ? Mine looks like it’s been going soft and sagging down the sides ! The machine is about 5 or 6 years old mind.
