E02 comes up on display on my dishwasher the model is Siemens sn25m830gb/02. Could it be a fuse, a relay or the heater pump it self and is there any way to test it or diagnose it?

Heater element shorted or drain pump failure.?

Error E02 indicates that the water temperature exceeded high limit.

Switch off the house circuit breakers dedicated to the water heater and then press the reset button located behind the control panel on the water heater.

Switch house circuit breakers back on.

If error persists, call a service engineer.

good luck

These seem like the siemens/bosch type. There is a heater relay that can go bad. Its in the front panel. Check the relays in the front panel for bad solder or burn marks.

The model number is usually plated on the left inside panel of the door, however, that is not always true and could be at the back which is hard to get to unless you take the dishwasher out.

The E02 error with Siemens dishwashers would mean the washing is happening without the heater turning on. This means the dishes may not be coming clean, the wash cycle is long and dishes do not dry.

It is linked to heater relay in control unit being faulty and could be also related to the heater itself being faulty. Worst case both are to be replaced.

A very costly affair. Would help if you can find the model number.

I think you already raised this problem and I have answered.

Thanks.

Take the control board out, open it up, and resolder the heater relay or replace the control. It may be under the recall and you can get a new control replaced for free.
