I have a zanussi fjd1666w machine that was not filling with water and pump was running all the time. I went into the engineer diagnostic mode and the machine filled with water ok but came up with error e33 so I think that the pressure switch may be faulty telling the machine that it is full of water when it isnt. Is there any way of testing the pressure switch using a multimeter. Also there are two switches in my machine a small black one and a larger white one that both have small tubing connected to them. I have blown down both tubes to ensure no blockages and both are ok.
Re: zanussi fjd1666w not filling with water
E33 can be caused by earth fault on heater element, you need to use a megger to check the insulation.
Otherwise pressure switches can be checked with multimeter – analogic should be (from memory) between 44Khz and 42.5Khz, white pressure switch will be simple open/closed. Also worth checking connections between these and the board.
Re: zanussi fjd1666w not filling with water
odom do you know what the 2 pressure switches are for. Also if I unplug the heater would that not eliminate that as being the fault
Re: zanussi fjd1666w not filling with water
dont blow into the analogic p/s (smaller black one), they dont like it much.
iirc the analogic is what regulates the filling etc, and cuts out various electric bits if something goes down, for safety reasons.
the analogue (big white one) is what is used to measure the amount of fill by varying the level of resistance it gives out, until it gets to either a max or a min.
is the analogue pressure switch a 3 tag or 4 tag? cos if its a 4 tag then it will have a 3-levels and be open/closed in 3 points of pressure and its important to measure it at each level – very difficult to guage when your breathing into it and trying to position the multimeter terminals at the same time.
as odom has said, heater elements both dryer and washing can cause odd error codes like E3*, but ive tended to get e36 as a rule if it was the dryer. thing is, the first few minutes of the cycle the machine will go thru a test run, just because its drainign and pumping means nothing other than ANY component has failed, inc the pcb. its almost like a default safemode so that the machine cant overfill or continue washing etc.
it does not automatically mean the p/s are at fault.
what you have to remember is depending on what part fails, if its gone more than 60secs into the wash, without filling its gonna sense theres no fill, which will give either an E1* or E3* faults. the problem with running the machine without any tags on elements is that you are running a live machine with the risk of :zap: which we would advise you never to do. the way to check the element before spending money on spares is to use specialist equipment as the aforementioned meggar to safely test the component without shocking yourself.
really depends what value you place on your life, or your customers???
Re: zanussi fjd1666w not filling with water
gandh1 thanks for reply. I cant get hold of my megger till I go back to work in new year so im stuck washing clothes round the in laws till then.
What I cant understand is that the machine passes test 5 in the diagnostic menu which is the heater test. The heter is working as I can feel the door is warm during the test and the water when drained is warm. Also I have the machine plugged direct into into a 30ma power breaker and it does not trip. The machine fails (E33) on test 7 which is when the pressure sensors are tested and max full spin which is why I thought it might be a pressure sensor fault. Looking forward to any other advice anyone can give till i get my megger.Re: zanussi fjd1666w not filling with water
l8 is the test procedure for the dryer, its it not possible rather than being at the end of l7 its pickign it up at the beginning of l8 ???
feel free to change pressure switches, no guarantees which if any have gone out, powerbreaker wont be affected by elements going out of parameters, because the difference is so low, its the electronics on the board that get grumpy because its not what they are programmed to ackwnoledge.
in the absesne of a megga, other thing to check is for reduced drainage – can sometimes cause error codes different to what they should be, uve probably checked filter, but also check recirculation pump – and behind drain pump, and the pump sometimes has a rubber flap that can get jammed backwards impeding drain flow
Re: zanussi fjd1666w not filling with water
gandh1 no it is deffo failing on test 7 and not at start of 8 because you have to manually press the button to start each diagnostic test. Dont think the drainage is a problem as i have half filled the machine with water using diagnostic test 1 then drained it and the water comes out as normal. Do you know if the big white pressure sensor is normally open or closed resistance as when i blow into it i hear it click and the resistance changes across two of the contacts but there are six wires on the sensor(two grey and one blue on one plug then two greys and a white on the other plug). My small black pressure sensor has three orange wires on it but i dont want to blow air in it to check as you said they dont like it.
Re: zanussi fjd1666w not filling with water
not the question i asked though marcus!
a little review of the situation:
you dont want to unnecessarily buy parts that have not failed.
you have no access to a meggar to test elements till new year
testing a 3 stage p/s requires the ability to hold your breath pressure, i.e bit like playing trumpet etc and i cant remember the exact confiurations of o/c an c/c between the 4 terminals
iirc the end of L7 it will drain to a level lower than the drum so the dryer can be actuated – this iirc is controlled by the white p/s not the analogic one, and of course, if its gone askew, will either drain all the water, or not enough out, either parameter will show up as a fault, because the p/s needs to recognise there is enough water to allow condensing to happen, other wise it will just create a lot of steam in the drum, or too much water which means when its drying it will just soak clothes, but iirc, its the analgic black ps that tells the elment whether its ok to kick in.
arrrgh, just drain the sump anyway and make sure, you might get rich regardless of whether its causing the issue 😀 at least then you can categorically guarantee its free from obstruction, at least until the meggar is available 😀
Re: zanussi fjd1666w not filling with water
OK managed to test the white pressure switch with multimeter while blowing down tube. Ist click anti boiling level went from open to closed circuit. 2nd click after a bit more blowing 1st level sensor went from open to closed circuit. Switch seems to be working OK. Managed to find a friend with same model washing machine as me so in luck i thought. Swapped both his pressure switches out and put in my machine but still not working so looks like it is either earth leak on heater or main pcb faulty. Will test heater on return to work with megger and hope that it fails as heater will be a lot cheaper than replacement board.
Re: zanussi fjd1666w not filling with water
😆 😆 😆 Washing machine now working fine.
Removed all plugs from circuit board. Blew compressed air down ends of all plugs and cleaned all contacts on pcb with RS cotton buds dipped in contact cleaner(solvent). Refiited all plugs back onto circuit board and fired machine up. All working a treat so far 3 washes completed. Thanks to all members that gave advice/info.
