Hobart Ecomax 502, getting very hot and switching off? Any help?

'reset'. It is a dishwasher, not a computer or cellphone. It has an electro-mechanical timer.

The BOF message on a Hobart Ecomax 652 dishwasher indicates a "boiler filling" issue, which means the dishwasher is unable to fill the boiler with water. Here are some things you can try:

1. Check the water supply: Make sure that the water supply to the dishwasher is turned on and there is enough water pressure. If there is low water pressure, it may cause the BOF message.
2. Check the water inlet valve: If the water inlet valve is not functioning properly, the dishwasher may not be able to fill the boiler with water. Make sure that the inlet valve is not clogged and is getting power.
3. Check the level probe: The level probe detects the water level in the dishwasher. If it is not working properly, the dishwasher may not be able to fill the boiler with water. Check the probe to ensure it is clean and in good condition.
4. Check the boiler: The BOF message may also indicate a problem with the boiler itself. Check the boiler to see if there is any damage or blockage.

If these steps do not solve the issue, it may be best to contact a professional technician to diagnose and fix the problem.

Boiler hasn't filled.

Remove the auto liquid , replace with water.
Start a washing cycle, wait two minutes till you hear the water filling inside. Open the door and pour a litre or so of Vinegar inside the machine. Let the rest of the cycle run.

This should clean out the inside of the machine if its not too bad. Otherwise you will have to find the "chemical sensor" and mechanically clean whatever is stopping it from sensing the water. It usually looks like two pencil ends about an inch apart.
If your machine looks "white" inside when its dry (from hard water) you might need a stronger cleaner than vinegar, or just try using two litres.

Hello. Have you find a wiring diagram for Ecomax 500-10 dishwasher ?

check the electrovalve, may have dirt stock on filter or the solenoid damage.

Hi, error 5 on a Hobart Ecomax CHF40 relates to a faulty thermostat, it isn't a common or generic problem with this model, i have found them to be very reliable, its possible the probe has scaled up which may have caused the problem. i can be contscted through www.easicook.co.uk if you need any further assistance
