Error F 57 - Bosch Logixx WFT 2806 Front Load Washer/Dryer

You do not state which HP printer you have but the 57 errors all indicate a problem with one fan or another. For instance, on an M4345 the 57.01 error would indicate that the cooling fan for the DC controller is not working.Here is a list of 57 errors by model Hp Error Code 57 Service Errors Codes 57 Tech Support

According to:

bassfisherman60

From the manual
02-57 Fan lock
This code is output when fan locking (over 30 seconds) is detected.
After the error message is displayed, the power turns off.

Perhaps opening the unit with the power unplugged (of course!) and clearing/cleaning the fan would help. It may be that the fan is just clogged with dust/debris.

F1 errors have to do with the finishing section. My code list doesn't go as high as 57.

Check to see if the finisher is connected properly to your copier. You should turn your copier off while inspecting it.

I got hold of another set of 56 and 57 Ink cartridges. By swapping the four of them in and out of two printers, I determined that one of the Black 57 cartridges was bad and caused a missleading error message to pop up saying to check the Color 57 cartridge. I don't know why I was getting different messages at first, but after several swaps in and out of two printers, the error message finally became consistant and I learned that the one Black 56 cartridge was the faulty guy. One Color 57 cartridge printed good but the other (newer one) left streaks on the Cyan and Magenta colors even after soaking the head surface for a few minutes and cleaning it with inkjet cleaner fluid.
The end result is that I have one good Color 57 cartridge and one good Black 56 cartridge which work good in two different printers.

By the way, can you email a labled pinout reference drawing of the hp56, 57 & 58 Ink Cartridges???

5 flashes is IK or current to cathode. check the IC's on the crt boards, check the focus block, check the vertcal deflection IC since the IK pulses come from the verticl cicuit.
