E90 Error
(MAKE SURE IT IS DISCONNECTED FROM THE MAIN POWER SUPPLY BEFORE YOU TAKE THE TOP COVER OFF)

This will happen if you turn your machine on its side or move. If you turn it on to a side sometimes a bit of water may have gone inside the electron circuit board on right side top. (when you take the cover off) All you have to do is just check all connectors are tight may be dry it with some compressed air. Just leave it for 12-24 hours and this error goes off.

I found this on a website while I was looking for the same information as you. Hope it helps.
Q: My Zanussi FJS1225W is showing an E90 error code, what does this mean?
A: I have had a few emails on this one, and 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, before calling an engineer in, or getting a spare 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.
