Hello,

Sorry but this device is specially made to be , so called , NOT FIXED!

You can still contact the shop/store where you bought the product and ask for a repair.

I have had this problem before and replacing the high voltage board ( that is the large board situated under the printer ) fixed it. However if you have replaced this board then I would agree that the water also took out the DC Controller Board.
The fuser probably did not need to be replaced.

E001 0000 Abnormally high temperature (detected by main thermistor)
The main thermistor detected an
abnormally high temperature (240 deg
C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.

E001 0001 Abnormally high temperature (detected by sub thermistor)
The sub thermistor detected an
abnormally high temperature (295 deg
C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.


E808 0000 Fixing drive circuit failure
- The heater does not turn on.
- A fixing drive motor failure was
detected.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the fixing drive motor.
- Replace the DC controller PCB.
- Replace the power supply PCB.

E001 0000 Abnormally high temperature (detected by main thermistor)
The main thermistor detected an
abnormally high temperature (240 deg
C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.

0001 Abnormally high temperature (detected by sub thermistor)
The sub thermistor detected an
abnormally high temperature (295 deg
C) during temperature control.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.


E003 0000 Abnormally low temperature (detected by main thermistor)
After the temperature detected by the
main thermistor has reached the
specified value, it does not reach the
specified value during initial rotation.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.

0001 Abnormally low temperature (detected by sub thermistor)
After the temperature detected by the
sub thermistor has reached the
specified value, it does not reach the
specified value during initial rotation.
- Check the connector of the fixing film unit.
- Replace the fixing film unit.
- Replace the DC controller PCB.

This means a printer motor error has occured. From the service manual: C developing disengaging motor rotation error.

To fix:

Developing disengaging motor
error
1 Reconnect the connectors J16 for the developing disengaging motor and J1100 for the DC controller PCB.
2 Replace the developing disengaging drive assembly.
3 Replace the DC controller PCB. Calibrate the printer after replacing the DC controller.

So, at the very least you'll need the developing disengaging drive assembly and, if that doesn't fix it, then you'll need the DC controller board. My bet is the DC controller has failed.

Sorry for the bad news, but please rate this solution as fixya even if it wasn't what you wanted to hear. Thanks.

According to what I have E800 is eith a problem with the Mains switch or DC controller. I doubt it's the switch but there are many things that would cause a DC controller error. You might try Hytec Board Repair for help on the DC controller. http://www.hytecrepair.com/
