Hi,
How can I troubleshoot this unit from the control board? Anyone have a tech sheet? I am getting a F-4 error code but the water seems hot! I did order a heater but like I said the water is hot! How else can I go about diagnosing this unit?

HI. F4 error code.
The element has been on too long (about 3 hours) and the water has not reached the required temperature. The product will abort the wash program, log the fault and report to the user.
PRIMARY ACTION – Check that the controller power connector and the heater plate connectors are properly fitted and the harness is not damaged. – Check the resistance between pins 1 and 2 of heater plate PCB, and if open circuit, replace the heater plate.
SECONDARY ACTION – Check the resistance between pins 1 and 2 of the controller power connector is about 10K at approx. 25oC / 77oC ambient room temperature. – If not (provided the harnesses are OK and the connectors are correctly fitted), replace the heater plate (bad temperature sensor).
TERTIARY ACTION – Replace the controller.
Let me know if you need any further assistance.
