Zanussi washing machine

E90 =cycle blocked suggest check pump/drain etc

I had the E90 problem about a year or so ago. Havng had a problem with my Zanussi dishwasher a common fault with zanussi white goods is that they don't solder major joints on the control boards very well. (Probably tryng to economise of the amount of solder they use)

Check all the connections on the control board are tight and haven't burnt off the solder. This worked for me and we haven't had this code since.

This error code seems to be the control board detecting a wrong configuration (in other words, an illogical set of sensing conditions, from its connected sensors and wiring). It apparently can happen, when wires become badly contacting, or if contaminated with motor brush carbon (the horrible black powder that comes off the motor commutator and brushes), or corroded from other contaminants from the soap dispenser area. You should be able to check this, remove, clean and replace the contacts:

it seems to be a common error code on some Zanussi models. This error code seems to be the control board detecting a wrong configuration (in other words, an illogical set of sensing conditions, from its connected sensors and wiring). It apparently can happen, when wires become badly contacting, or if contaminated with motor brush carbon (the horrible black powder that comes off the motor commutator and brushes), or corroded from other contaminants from the soap dispenser area. You should be able to check this, remove, clean and replace the contacts: Take the top off the machine, (ENSURE IT IS UNPLUGGED) and on the right hand side of the machine, you should see a set of 4 blue wires that go from the electronics module to the front display unit. Take this plug off (it is held on by plastic retainers) clean with wd40, or silicone (Servisol) contact cleaner, then dry, replace, then try again. If it is very badly corroded or pitted, you may have to replace that part of the wiring and socket.
If it is not that, then the wiring to/from various other sensors could be damaged, or the control board could be faulty. It is probably worth checking around other plugs and sockets, re-seating each one in turn, that lead to the control board, as they are expensive (£60 - £80). Pulling off and plugging back on (Re-seating) the plugs and sockets has the effect of cleaning the contacts, and may fix certain intermittent faults like this. Obviously check for any plugs/sockets that appear burnt, corroded, or discoloured compared with the others, and clean the contacts with emery or a needle file.hope this helps pls do let me know

Error E20 means the machine has failed to pump out. 1st check the filter at the bottom right hand side there may still be water inside if so pull the grey tab to the left of the filter there should be a thin hose extend it put it into a shallow dish and pull the cap off to let the water drain this may be a slow process. When the filters out look into the hole with a torch to see if any obstructions in the pump impeller this looks like a cross. If the filters and pump are clear it may be the pump has failed.

yes sounds like door interlock cheap and easy diy job goodluck and unplug regards jason

check the drain hole when you start the machine if the water is coming back out , if yes that means your dump valve is bad.

Click on Zanussi (below FIXYA) on this website, type in your model No & search. You will get a shortlist; click on your model,below the page u will get Manual/Guides. Click on the blue, you have your manual on line.

an E90 fault is a problem relating to the main control module found behind the front facia. it could just be a bad connection on the board connections though
