Hi collective brains... Hope you can help me..

I have a slimline beko dishwasher at home that seems to have a burnt out winding on the main recirculation pump motor.

I want to repair it on the cheap and so have been looking at second hand pumps.

I've found one that is from a beko and looks identical but is rated at 125w rather than 90w which mine is.

This equates to about 0.15A.

My questions are.

1. Would the supply for the pump come from the pcb?

2. If so would this extra load be a problem and cause the pcb to fail?

Thanks as always. Jim.

Bumpity...

Supply to pump would likely be triggered by PCB but the load voltage would not, so answer to #2 would be no. But this is all guess work on my part. If you check inside the body of your machine you will usually find the wiring diagram taped to the side of the body somewhere? this will tell you, Or just follow the wires back from the pump to see where the feed comes from?

I would think that if its physically the same, that it will not cause any problem. I used to carry a Beko wash pump as van stock, used them on many different models over the years. NEVER checked the wattage, a relay on the PCB will be carrying the current, I would assume that Beko have upgraded the pump, especially as they had a highish failure rate a few years ago when I was still working in the business.

Thanks guys. What you both say makes sense.

I think you may be right jbw. It could be an upgrade due to a high failure rate. The pumps look identical in both ratings. Think I'll give it a go.

Having worked as a service engineer for several major appliance manufactures over the years, the parts are "improved" in their speak, because modified infers there was a problem, but manufactures have a fine balance between failure rates and production costs. In the case of Beko their appliances have improved significantly over the last 15 years, apparently they are now no. 1 in UK appliance sales.

 

Hope you get it working OK.

Thanks. Hopefully I will get it working. I'm fed up with washing up by hand. I'm assuming it is the motor. I changed the capacitor without success and it's measuring a dis across the motor terminals so that would suggest the motor wouldn't it? Is there any chance that the motor blowing would also fry the pcb?

[JBW]

Only recall one taking the PCB out, usual cause of wash pump failure was leaking from shaft seal and the motor seizing up.

Just think about the actual current flow, 90W at 240V = 0.375A where as 125W at 240V = 0.52A.  I've used 240V as although the declared supply voltage is 230V in the UK it tends to be a little higher in practice.

 

As you can see the difference in current is negligable so I wouldn't be overly concerned.

Ta folks.
