I have a Electrolux dishwasher model eucaimlg, and it has been started up after some months standstill. It starts fill and water temp goes from 16 to 18 degrees and then it stops after 5-10 min with message A-1. Seems like it stops just before the heating part, but not sure. I have checked the overflow pipe, but cannot see any issues.
It is +10 years, and no unusual sounds. Could it be a thermostatic issue?
Sadly that is a commercial appliance that I and I expect, most here don’t have access to any info for as the commercial arm of Electrolux is a totally separate entity to the domestic one.
