jet wash action not dry f4 fuction?

Jawfer.

It would help no end to have at least some clue what you are talking about.

As far as one can make out, you have a washer/dryer of some kind but, for some reason, you decided not to tell us the make and model.

The machine appears to complete the wash but does not dry. You see briefly "F4" on the display and the machine switches off.

Please confirm if that interpretation of the gibberish you wrote is correct or correct it if necessary. Please also tell us the make and model of the machine with which you have a problem.

Before you do any of that, however, please do a simple Google search for "Make Model F4 error" (replacing "make" and "model" with your own information) and see if you can help YOURSELF even a tiny bit.
