Cs546 I have cs code546 and I have tried hitting the clear button and nothing chjanges on the error message. I can't clear it.

To reset waste tank full error in MP730.

1. Hit the "menu": Key
2. Hit "Copy" Key
3. Hit "#" Key
4. Scroll thru the menu headings until you come to "Test Mode" - 12th heading
5. Hit the "3" button- this will bring up Eprom Clear
6. Hit "0" button
7. Hit the "Stop" button

H4 is nothing but an error code that appears due to power fluctation(in absence of a stabilizer). You please enter # interrupt-C interrupt -14-start to clear to clear the error

the co ordinates of touch screen may have disturbed try, touching surrounding area of clear button or replace touch screen.

try reinitializing main pcb

are you sure it is 620? not 6020 or 6200?
try hitting 1087 two times on the keypad, that is maintenance mode now type 906 and start button or execute and start button. that will reset a fusing code. that is the only way to reset those codes for safety reasons.

I had the same exact thing happen...I put in some popcorn, it wouldn't pop. The screen said "sensor error". I tried heating water, a piece of chicken...nothing would heat. I unplugged it, plugged it back in...nothing. The manual says to close the door and hit the clear/cancel button. I could have sworn I had done that, but my wife simply hit the clear button and it started working again good as new. Hope yours does the same. : ))

You most likely have a defective "yellow" PCU . Try replacing that.
Otherwise you have a high voltage problem

Can only try

get the firmware on the phone reflash or do a master clear and reset.
