Hotpoint Dishwasher DWF34

[Gimli]

The dishwasher fails to clean completely.
The spray arms do not appear to move although they do spin freely.
I have cleaned the filters and spray arms.
The machine previously worked fine.
Also the power point RCCB has tripped while the machine is on, although this might be coincidence.
Any suggestions welcome as to the problem.
Thanks,
Gimli.

Possible blockages in internal hoses or the main circulation pump impellor adrift, a Bosch machine, decent quality but difficult to access, please remove the plug if you intend to have a look inside, or try the link below to see if we have someone in your area.

Thanks Jim
The machine appears to fill, drain and heat ok so I suspect the main circulation pump. Does this machine have separate pumps for cleaning and draining?
Assuming it is the pump can I fix the impellor or will I need to replace the pump?
Do I access this from inside the machine or underneath?
I have just done another test run and the spray arms definately are not moving but everything alse seems ok.
Unfortunately, having checked my postcode, you have no one in my area.
Thanks again for your help and apologies for all the questions.

Can you actually hear the circulation motor running, or is there just a faint humming noise?

As I said, difficult machine to access, if you have to get at the main circulation motor, then the door.side panels and complete inner cabinet have to be removed. Post up the area you live in, Dave Conway or others may be able to give you details of a reputable company in your area.

Penguin 45, thanks for your interest.
The operation of the machine sounds normal to me so I assume the motor is running, not just humming.
Does this suggest the problem is elsewhere?
Thanks,

No, that suggests the problem is more than likely either an internal blockage or a faulty circulation pump as first indicated. It is not unknown for the impellor to come adrift of the motor shaft. There is a circulation pump impellor & seal replacement kit available that is reasonably priced. Unfortunately the only way to determine this fault is to open the patient up.
