I will describe your experience with E09, just today it ended happily.
A dozen days ago my dishwasher SPV53M10 caused the disconnection of the circuit fuse in the kitchen during cleaning. There was a storm on that day. After turning on the power, the dishwasher finished the program, but unfortunately the error E09 jumped out and in the middle everything is cold - the heater got off. Dishwasher production year 2011 or 2012, after warranty. In this model, the heater integrated with the pump, the cost of the part itself, about PLN 600 plus repair probably about PLN 800. I have already started looking for a new dishwasher, but I remembered that I have an insured flat, the policy is, among others, equipment insurance rtv, adg from surges. I reported damage to the insurer, an appraiser from the service came and repaired me as part of the home insurance. Of course, all this took a while, because from the failure to repair 20 days, but thanks to this I missed a considerable repair cost. I suggest you take advantage of the insurance contract, when the damage happened, you finally pay the premium.
