Bosch WTL5400 Condensation Dryer

Sounds like something's blocking the hot damp air being removed from the drier. If you are confident enough, go through the drier vent system looking for a blockage. If not get a good DIY neighbour or appliance engineer. Silly question, is the drum turning?

I have the same problem, the dial to select the dry program is making a bad contact causing it to stop. Try using a different program.

I tried to clean the dial but it didn't help.

I have owned the same dryer for about a year and just started having this F03 problem. The condensation drain hose is the soft flexible rubber hose coming out of the back of the dryer and it drains into the same drain as a washer. It's easy to pull the hose off its connector at the back of the dryer and just blow hard into it to make sure there's no lint clogging the hose and reconnect it to the dryer. Next open the panel on the left of the dryer and thoroughly rinse (water only, no soap) clean the two parts behind the door (first is plastic and behind that is the condensation filter which probably is loaded with lint). Sometimes the lint in the condensation filter channels (those that run from front to back) can be quite stuck. Use a long pipe cleaner to get in there or a garden hose with a spray nozzle. Shake the excess water out of the condensation filter and dry off the outsides of two parts. Clean all the lint out the compartment where the parts go. There is one more crucial step not mentioned in the manual. 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 or a blunt table knife under the panel and gently pop it open. Under the panel is a small chamber that you can't see very well 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. Use paper towel to get it all out. Blow hard into the dryer through the condensation hose to clear up any last bits. Pop the panel back in place as well as the condensation filter and the plastic part. Take out the lint filter (within the dryer drum compartment) and wash it with soap and water. Use an old toothbrush or something to clean the screens thoroughly. Rinse well and dry it completely. Clean all the lint out of the empty compartment. Put all three parts back into the dryer. Clean all lint off the door. Using paper towel moistened with white vinegar clean the two metal sensors in drum compartment on the front wall and lower left. Run the dryer empty but with heat on for a few minutes to make sure all the water is drained out. Now try drying a load. I think it's a good idea to rinse clean the condensation filter at least once a month since it collects a lot of lint. Hope this works for you.

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.

This is a common complaint with this dryer.The probe generating this problem,is at fault.It likely has a film on it,from the dryer sheets.Remove the lint screen,and wipe down the probe that sticks into the air box.Should fix the problem,if not ,replace the probe.

bad sensor or dirty

I posted in late December on the lint alarm and what I discovered was a bit alarming. (no pun intended) Lint had been accumulating on and around the heating coils used to dry our clothes. Some of the lint was burnt and the remainder, amounting to a small handful, was caught up in other area's around the lint sensor. After carefully cleaning the heating coils (with a tooth brush) and removing the rest of the lint and successfully putting everything back together, we have not had a lint alarm issue since. (Touch wood). No need to replace the lint sensor or any other parts. It was not that hard to take apart the back and remove the heating coils to clean, but it requires the unit to be unplugged, careful attention to what came off and where it goes back on. After what I found, I will be cleaning the heater coils out once a year. Which then raises the question. Should a person have to do this? The obvious answer is no! But from time to time we buy things that are not what we would expect and do what we need to do to make it work. From what I can tell, lint is getting past the lint filter and ending up where it shouldn't be. Hope this helps any of you that are having the same issue.

have you checked the vent line it could be stopped up if the line is bent same affect as the lint filter being full
