Zanussi ZDV12002FA Dishwasher Not Heating

[electrofix]

water flow problems, lack of water and heater is on for some reason, lime scale build up or because it wants to

you have to understand all these heaters have safety fuses so in thee vent of the heater coming on with little or no water then the fuses blow to prevent fire

Hi,
Have same problem with overfilling. The cycle stars and finishs with the overfilling via two little black hoses that activates the antiflow system. Read about your replacement of presure sensor. Have information about this? How to check it or knowing that is the problem?

some of these units have pressure sensor modifications
will need model and PNC number to check if yours is covered

it was done to stop the pressure sensor blocking up and giving false readings

Ok, is the one on the left. Any information of how to dismount it and how to checking if It is working
Thanks a lot!

in that case order the kit and fit it. if it does not cause problems now it will in the future

there is a small hole where the water pressure activates the switch and it clogs up causing problems. the switch clips on to the sump the other side of that hole

Sziasztok! Új vagyok a fórumon így elnézést ha valamit nem tudok. Ugyanilyen készüléken ugyanez a hibajelenség van miszerint nem melegíti a vizet fel. Kicseréltem a fűtő egységet, de kimérve a leírtak alapján az előző is jó volt mert 25 ohm értéke volt. Megmértem a hőmérséklet szenzort ami 20 fokon kb 3,8k ohm volt. Hajszárítóval próbálva szépen csökken melegre aztán visszaáll. Ezen felül hogy tudom kizárni a hibákat és megtalálni a hibás alkatrészt? Köszönöm a segítséget.

Hello! I’m new to the forum so sorry if I don’t know anything. I have the same problem on the same device, that it doesn’t heat the water. I replaced the heating unit, but based on the measurements, the previous one was also good because it had a value of 25 ohms. I measured the temperature sensor, which was about 3.8k ohms at 20 degrees. When I tried it with a hair dryer, it drops nicely to warm and then returns. In addition, how can I rule out errors and find the faulty component? Thank you for your help.

if its exactly the same unit there is a tacho coil on the back of the motor that goes open circuit. if this goes it wont heat

zanussi dont supply the part but the beko coil fits ok
