hi there anyone,
need help with my dishwasher, its a prima lpr600 whirlpool in disguise. i have read it on various bits while’investigating’
basically i have learnt from the previous requests and answers posted and have found as follows.
the dishwasher stopped during the cycle possibly at the end (as inside was hot and looked clean)and bleeped continuously with a flashing power light pulsing 4 times then pausing, which from what i have read means a flood in the bottom tray, but its dry down below?
i felt that after reading someone’s comments regarding the float switch mechanism together with the fact that my machine then started to keep pumping constantly to empty and not do nothing else!, that possibly i had a faulty float switch? it doesnt move on to the water fill etc for the normal cycle, it would just try to pump out for a period, then stop and bleep, with the 4 flashes.
anyway, when i looked for anything resembling a float switch, i firstly disconnected the mains, and then couldnt find any switch, but when i switched the washer back on, it seems to work now?, so being a pain to get to the bottom, i would rather fix it if i can. could i have a faulty float switch, and is this something easily changeable?Re: prima lpr 600 location of A float switch mechanism
There is no float switch in your appliance.
F4 specifically means that the computer has not detected a drop in the water level in the machine within a pre-set time. This can be caused by the machine not draining (blockage/pump failure), or the water level switch not telling the computer that the level has dropped.
Look into the sump – at the three o’clock position you will see a black grid. This is the water indicator. It is a daiphragm switch device and it is very common for the grid to become choked with fat deposits, thus jamming the works in the full position. If it looks choked, attack with hot water and a toothbrush as you may be able to scrub it clear. If not, it’s a twist fit from underneath for replacement.
Power off, first please.

Re: prima lpr 600 location of A float switch mechanism
thanks for replying so quickly, this is the first time i have tried a forum, particularly this one, which came as recommendation,
anyway,as far as i can see until i next try a full cycle, the machine seems to work, but i checked the grid as you said, and i couldnt see any fat in it, however as a precaution, i flushed plenty of hot water through it and kept putting the drain on to empty, which it emtied a full sump in a couple or three seconds, so i will give it a go now and see what happens next full wash.
i would imagine that dirt and grime is the biggest cause of problems in these things, as i was in a friends last week and noticed hers, while she was emtying it, and to be honest, i refused a cup of tea after seeing the state of it! but mine is pretty much as neww inside, and is always full of salt and rinse aid etc, as i look after my gear. i was happy to see it was a whirlpool though, as i had believed it was some sort of naff thing that came free with the kitchen in some offer at the time.
i will post again if the problem is still there after replacing the swith you mentioned
thanks again
