C8 fault code - Electrolux Dishwashers

The P8 fault can mean many things when it pops up on your Mitsubishi Electric wall controller. The P8 fault is activated when the indoor coil sensor does not change the temperature for a set amount of time after the compressor is (or should be) switched on.

You will need to take it to a tech to look at the diagnostic codes. Anything else based on the limited info you have given would be a complete guess. Common faults are sensors failing.

What causes the P8 error code? As we mentioned above, the P8 fault can mean many things when it pops up on your Mitsubishi Electric wall controller. The P8 fault is activated when the indoor coil sensor does not change the temperature for a set amount of time after the compressor is (or should be) switched

code p0171 refers to system to lean bank 1==causes intake /exhaust leak--AIR system--MAP/MAF sensor--fuel pressure/pump--injectors--HO2s Have a fuel pressure test done on the fuel manifold to check for blocked filter/faulty pump/fuel pressure regulator faults
code p0174 refers to system to lean bank 2 --same causes including hose connection/s
code p0420 refers to catalytic converter system -bank 1 efficiency below threshold==causes catalytic converter--wiring--HO23. Check the cat converter is not cracked inside and the oxygen sensor is working.

ricoh c8 problem solution

sounds like an earth problem, check the earth cable to the engine.

If there is a set button hold it for 5 seconds.
C8 means that at the rinse phase the boiler did not empty.
The reasons are ..
1) the nozzles are blockled
2)Drain pump out of order
now you must reset c8 from the parameter in order to start again the dishwasher

C8 is the last stop in the point of burner ignition and a total of eight error codes. Error code 12 is a supplemental code that means your LP gas supply is too low...have your LP tank service and try again.

a C8 warning means the (Thermister) temperature sensing device has shorted or is open circuit, this replaces the old-fashioned thermostat that they used to fit. the water in your m/c could either stay cold or boil.
