I really need your help please, my husband cant strip a Harley Davidson motorbike and put it all back together but this Prima LPR 600 Dishwasher has got him beat.
It started when I did a wash on 50 and at the end of the cycle it just starting beeping like crazy and I had to shut it off for the beeping to stop, didn’t think anything of it until I tried to use it again and it wouldn’t work and started flashing fault 4 which I know to be a draining problem.
my husband opened up the bottom front panel and we could see the tray was full of water, we established that the hose on the pump was split and was told by several shops we had to buy the whole part and you could not get a pipe to fit it but the part was expensive, hence my husband found a hose of a cosworth car, cleaned it all out and fitted the pipe with jubilee clips.
With the f4 being a draining problem while we had the dishwasher open we checked the sump black vent thingy for debris we checked the waste hose where it was connected to the sink and the dishwasher, we also unscrewed the bit by the sum where it has a o ring even cleaned under there we checked everything for blockages and found nothing, I’m always using dishwasher cleaner so there was no part on my dishwasher not even the hose that was full on gunk it was all clean.
So my husband put it back together and loads of scratches to his arms and hands later we set it off on a cycle, I had another dishwasher cleaner so I run that through on a 70 wash and it was all running smoothly until right at the end once again it started beeping like crazy and F4 fault appeared again.
I reset it and tried just a rinse, what happens is it empties for a few seconds then starts to fill up but only a few seconds then empties again, but just continues to empty until the beebs continuously sound and F4 flashes again, basically it wont fill up just keeps emptying.By this time we had had enough we had been working on the dishwasher for days to no avail, my husband said there was a (I think) a valve on the motor where he attached the hose and maybe he did a too good of a job and put it on too tight so he went back in undone it a bit and re did it again, the dishwasher is no longer leaking, I think it was a coincidence, I think the hose was split also alongside the F4 problem so even when the hose was fixed the F4 problem was still there, but like I said we have been through everything and checked for blockages and found nothing.
Do you know if we have missed something, can you help, I would be very grateful for any help you can give me, thanks in advance xxx
Re: PRIMA LPR 600
weve kept on trying to find the solution and come up with the water inlet valve, we tested it with a electric meter and its dead so now we are thinking the inlet valve is the problem why the dishwasher wont fill up, weve took of the pressure switch and cleaned that and tested that with an electric meter and that’s works ok, so the only problem we can think is the inlet valve, if any of you can shed any light on this I would appreciate your help thanks guys xx
Re: PRIMA LPR 600
well guys just keeping you updated on the progress of this prima lpr600 nightmare of a dishwasher ha ha.
recap… split pump hose originally replaced with a pipe from a cosworth car. now this is the initial problem where it all started but had a knock on effect to other problems.
further problems once fixed the hose put on a cycle when got to the end it started beeping like crazy and appeared with fault 4, however f4 is a draining problem and there is no problem with any draining so we know that the fault code is incorrect.
the prima lpr600 works with a certain amount of water in the pipes always, its designed to stand with water still in the pipes even when not in use so what happened with ours is when we had the split pipe the water that was designed to stay in came out and even when tried to put on a cycle it started filling up but then just kept trying to empty until in the end it beeped like crazy and F4 happened again.
so what we did was put it on a cycle, 1st it starts to empty out the stagnant water that would have been in from a previous wash then it should start to fill up, but is dosent, so when it starts to fill up open the door and manually with a bucket fill it up to the seal obviously not more than the seal as it will start to come out, then shut the door, with ours it started to proceed to wash and empty like usual and not beep like mad, so once again when it was time to fill up with water we filled it manually with a bucket and it proceeded to carry on with the wash.
once full up, where all the water in the system had flushed out due to the hose spilt all this water was now back in so machine was running smoothly and did so for x3 cycles, then at the end of the cycle it stated flashing f4 fault again but we no this is totally wrong as there is no draining failure.
we never changed the inlet valve even thought it was giving no reading on the electric meter but researched into it a bit more.
basically the control panel could be dodgy now thus giving out the f4 failure but we are just going to keep on using the dishwasher and even at the end of every cycle it starts beeping as long as its at the end of the cycle and it washing the dishes and I know its not leaking i’ll just keep using it, but our next step in the mean time will be to find a cheap inlet valve and change that to see if any change with that.
I hope all my rambling on is helping you in some way and I will keep you posted on any further progress… but if you know more than me I would appreciate any help you can give. thank you xx
Re: PRIMA LPR 600
well these prima dishwashers are a nightmare of parts and problems, what we have been through trying to save some money has been so stressful lol just wanted to make sure I told you guys in case your all having the same problems, i’m just waiting for the dishwasher to fill up with dirty dishes so I can try it again and probably will be extending my experiences with you all over again if it doesn’t work ha ha cheers xxx
Re: PRIMA LPR 600
well guys dishwasher all fixed…..we only had to replace the hose as stated above and basically it was not the inlet valve as well, it was all down to the dishwasher just get emptying and we had to manually add the water before it had chance to empty. once the dishwasher realised it had water in it, it then proceeded to carry on with the cycle. so once we fixed the hose added the water manually it stopped beeping like mad on an F4 fault.
I hope all my ramblings and going on help you, as its been a nightmare to try and find what was wrong. but got there in the end.
take care and best wishes xxx
