Getting a E04 error code - Siemens WFXD5200UC Front Load Washer

The error code E04 on a JVC Camcorder GR-AX2 indicates a problem with the cassette mechanism. This could be caused by a number of issues, such as a jammed cassette, a malfunctioning cassette compartment, or a problem with the camcorder's loading mechanism. In order to fix the issue, the camcorder may need to be serviced by a professional. In the meantime, you can try removing the cassette and reinserting it to see if that resolves the problem.

good luck

Reset code in service mode F9/ram initialize/fuser reset/reset power

How do I clear machine error code E04-01 on a Panasonic DP-3030 photocopier?

E 4-01 is a fuser error that only can be reset in service mode F9 reset fuser

If your standing facing the back of the machine, you will need to change the top right fan that cools the IH,power supp. there are two fans which need to be replaced, the other fan is behind the sc pcb but that will give a different error.

the best thing that u do first is to clean the fuser unit, esp. the thermostat located there. then you may go to service mode, (function+orig.size+3), F9, look for ram initialize, then look for LBP FUSER RESET.
it will reset all e4 machine error.

Lisa, E04 is an error code which shows that one or both of the reels has stopped during play or record operation. We find that tapes with liquid contamination can stick to internal parts in the mechanism causing this error. Try another tape, if this does not resolve the problem something is defective in the tape transport. Good Luck to you! Joe Weibel customelectronics.org
