Diplomat/Whirlpool ADP8322 – no pressure/arms not spinning..

Hi Guru’s,

I have a whirlpool/diplomat ADP8322 and having some issues I was hoping someone could help me with.

bottom spray arm :
Basically the spray arms are not rotaing or are moving on and off at 0.000009 mph. the water outlet is the same very weak, though it will suddenly have a burst for a second and then back to a trickle.

middle/top :
no movement – no water

I have even taken off the spray arms to see if water gushes out of the bottom, no just a little bubbling….

I have cleaned the arms and tubes

I think it may be the pump, but I am not convinced as its working but just very weak. I heard this can be fixed rather than replaced…

Any Ideas…

Many Many thanks in advance
Raj
