Try to vacuum clean inside the door contact breaker (female part). If you can remove the dust it should start working again.

I found this on justanswer.com, I am going to try it this weekend and I will post an update.

"Ok if you remove the left hand side panel then located at the back is the drain pump
remove the hose on it which goes up to the bottle and blow up it to make sure its clear.
If thats fine then remove the pump and clear any fluff thats in there and make sure the impeller is ok and turning fine.
Then refit and try again hopefully this should sort it out.
let me know if you need anymore info."

the thermostats at the element have to be replaced, they burn out prematurely if the condensor unit is not cleaned on a regular basis.

Hi
You need to remove the left side panel, this is the side where the drain container is, once removed you will see the drain pump with two pipes coming from it, remove the pipes and top cover, disconnect the wiring, remove the pump unit with the clip, clean the float unit and pump, also remove the congealed mess in the water trouth as this is what holds the float up and makes the machine think the drain container is full.
I bet you will find this will cure the problems you are having, it did with mine.

For the F:03 problem on the Bosch Axxis (WTE86300US) do all the things mentioned in Solution #1 above. Sometimes the lint in the condensation filter channels (those that run from front to back)can be quite stuck. Use a pipe cleaner to get in there or a garden hose with a spray nozzle. However there is one more crucial step not mentioned in the manual or in Solution #1. Once you remove the condensation filter you will see a small plastic panel on the lower wall of the condensation filter slot. Slide a flat blade screwdriver and gently pop it open. Under the panel is a small chamber where you will find a slurry of lint/water which is what clogs the condensation outlet. With latex gloves reach in there and clean it out. Blow hard into the dryer through the condensation hose to clear up any last bits. Pop the panel back in place. This should fix your problem.
