Beko Dishwasher pump doesn’t run

[russell_nash]

My Beko Dishwasher DIN 16310 circulation pump doesn’t run. It is clean inside, receives 230V the whole time and on the other two contacts receives a 5V AC signal constantly rising to 14V AC when water starts filling. The pump is an Acrelik 1783900400. I am wondering if those voltages represent a normal signal to start? If they do the pump is faulty and if not it isn’t. Anybody any idea?

tried to look it up but you have a wrong model no

it will have a commercial code something like 7621051642

this is a digital motor its fed 240v but the other signal comes from the board to tell it to start and sometimes what speed

in your case i cant be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} certain but it will be an inverter failure inside the motor. if you strip it you may find damaged components if they are visible

Yes, I did wonder about the number but that is what is written on the original Beko receipt under Model Number. The serial number is 1850004301. Thanks for that information, I did look at the PCB and there is nothing visibly damaged. I would be fine with de-soldering and soldering a new inverter but without a schematic it is difficult. What I really wanted to know is if I would be wasting my time by buying a new motor, which it seems not.

Thank you.

I first had the problem over 6 months ago. The connectors to the pump each had a corroded contact, they are plated, not just copper. I cleaned them up and then it worked again, but occasionally the pump didn’t run. I think that probably was just coincidence and the motor was intermittently not starting because of the electronic problem.

whenever you take numbers fir any machine you have to take it off the label on the machine as reciepts and owners books are not accurate enough to reliably order parts

if i has an accurate model and serial no i could look up the correct motor part no and check for any tech bulletins to see if there is a common failure

if you serial no is correct the unit was build jan 18

Thanks for the offer, when I take the pump out again I will see if I can find a label. I have already found a source for a replacement pump. Yes, it the machine was bought in 2018 according to the receipt.

the model number is on the frame of the machine usually round the door rim

the number on the motor will be a number from the manufacturer which wont be Beko

Dave

[russell_nash]

On the right-hand side of the door rim is a sticker, there are two numbers on it, DIN16310 and 96603.

[electrofix]

no does not exist

there is a DIN15310 but not above no

there is a commercial code if model is DIN15310 it would be 7630463877

Hello Dave. I can only read what it says on the label. So I replaced the pump and now instead of being silent you can hear a dum, dum, dum sound, so the pump seems to be running but little to no water is coming out, it doesn’t spray in your face when you open the door and nothing is clean at the end of the cycle. Somehow I am not surprised that it isn’t that easy. :p Do you have any idea what else could be the problem? I am in a hard water area but all plastic parts and pipes are as clean as new.

jumping the gun a bit by replacing the pump without checking its the fault

was it new or used,

is it getting warm after you run it

trying to work out if the pump is being energised

have you opened it 5 mins in and see if any water going in

I those are the normal values to make the pump run then it is being energised, but I can only measure at the connectors while disconnected because I cant access under the machine while it is running.

Was what new or used?
The machine gets warm enough to generate steam in it.
When I open the machine no water is going in, but before opening it sounds like the pump is running.

ok dont get mixed up between drain pump and wash pump

when you first start a progamme the drain pump runs then it fills. some people assume is the wash pump thats running but often it doesn’t.

from there the water enters and the wash pump is started after that

I forgot the style of pump you had and to make things more difficult I cant access Beko Tech anymore

your pump is the digital version. its supplied by a constant mains feed then down the data wires the pcb tells the pump what to do and when

faulures can be either the motor itself, the data wiring to the control board or the control board

So we are talking about the wash pump. I had the idea to stick a screwdriver in the door lock opening of the door. It suddenly made much more water run from the washblade connections, I had removed them to better see how much water comes out and to have less spray. So if I bridge the door lock, the problem seems to be solved. Strange because otherwise the door lock was functioning when opening and closing the door.

[electrofix]

it may be funcioning mecanically but not electrically

Dave

So I managed to make the door switch, the mechanical plastic part, work properly with some oil and moving it backward and forwards. The NO microswitch is fine. When I tried Programme 2,3, and 4 they seemed to work fine and the normal volume of water came out of the washblades. Every time I ended the cycle by holding the P button until it cancelled. I thought I was done.
One thing that was noticeable is when I ran P4 a puddle of white foam was at the bottom of the machine. Never seen that before. Then something strange happened, when i choose any programme other than P1, it switches to P1 when I close the door. It then makes a continuous drain pump noise which never goes away. The P1 switches to the cycle end arrow after a few minutes and beeps three time, as though the cycle has ended but it still runs the drain pump, or at least that is what the constant humming sounds like. It does this every time now. This problem never happened before.
I did wonder if the constant door opening had damaged wires in the door wire bundle. I found two wires with a kink in, i cut then on the kink, stripped them and connected them back together, as there is a chance they were broken inside the insulation, but it had no effect..It is really turning out to be never ending.
Thank you for the replies, Dave.
