Lamona dishwasher

Have a Lamona dishwasher which is not heating the water,I have replaced the heating element.but it has not solved the problem. Can anyone help please.

Sorry but I cannot find any tech info on this unit.

It looks like a European model and I only have access to North American products.

One thing to check is that most unit have a hi-limit thermostat in the heater circuit. This is usually attached to the bottom of the tub.
You should be able to trace the heater wires back to find it if the unit has this.

Most American units have a tech sheet/wiring diagram.
Often it is attached to the back of the kick plate.
I would check the unit to see if you can find it.

With luck someone else will jump in with the help you need.

Thank-you for your time helping me,I will check this out as you suggest.Thanks
