Lint filter going off after 5 minutes then shutdown
This is a condensation dryer(NO VENT). Is this lint filter sensor the one that is in the bottom of the vent holes(towards heat exchanger) that looks like a metal probe sticking up as you look into the front of the dryer? How about disabling this?

Re: Lint filter going off after 5 minutes then shutdown
Hello folks try this if you have not gotten this resolved. Your dryers have 2 sensor systems, the first one test the clothes for moisture, the second for the heat. The 1 sensor system drops resistance when the wet clothes are put in the dryer. the shutting down after 5 minutes and lint filter light coming on could be that the dryer isn't sensing the moisture. Now for the fun part, the entire inside of the drum and paddles is the moisture sensor. Try cleaning the inside of the drum with a cleaner to remove any detergent or fabric softner residue. This is crucial if you are using fabric softner sheets as they coat the drum. Also wash the lint filter with soap and water so the water goes straight thru instead of puddling up. Remember to also clean the condenser as this can trigger this issue as well. Hope this helps
Re: Lint filter going off after 5 minutes then shutdown
As one other solution suggested, run water over your filter. If it pools, the filter is clogged (even if it looks fine). I ran some soap over it with a qtip, and seconds later the water was going straight through. And so far, no lint filter alarm!

Clean your lint filter, and clean the entire line vent from the dryer to the outside export port, also look inside the dryer vent hook up for obstructions and remove any lint. Keeping these parts lint free will save you energy and also drying time and maintenance repairs. My dryer is 18 years old.
F1 Condensate drain overfilling.
1. Check condensate reservoir pump and drain tube.
F2 Maximum drying time exceeded (3hrs) 1. Check for tripped circuit breaker or blown fuse
2. Check ductwork for lint build-up
3. Check hi-limit and cycling thermostat
4. Check heating element
F3 Thermistor fault 1. Open thermistor, replace
2. Bad wiring to thermistor
F4 Too much lint in the lint filter, front housing, or in the condenser.1. Clean lint from lint filter and/or condenser
F5 Fault in the moisture sensor · Lint covering sensor in front of housing1. Bad sensor
2. Bad wiring to sensor
if its a condenser dryer make sure the condenser itself is not blocked up ( usually located at bottom of dryer, looks like a metal box). clear any lint build up and u can also flush it through with water. obviously check the filter also.
if a vented dryer make sure the vent hose not kinked or blocked, check the actual vent outside on your wall as wel. sometimes if wrong vent fitted ie one with wire mesh meant for extracter fan, can be blocked up with lint
When a gas dryer starts and the burner does not stay lit more than one minute the flame sensor is not detecting the flame to as a by design safety feature the burner is automatically shut off. It is not sensing flame so it is shut off.
BEFORE you change this part make sure that the outside vent flapper and the ducting form the back of the dryer is free of lint. Disconnect the dryer vent and try it with nothing connected to the dryer. Also check around the lint filter area for lint especially in the bottom. If there is not a lint or ducting problem then by all means change the flame sensor.
Have you taken the condenser itself out from the bottom of the machine? Remove the condenser from the bottom door and rotate the clamp tags which secure it in. Slide condenser out (aluminium mutli-finned box assembly) and carefully take it outside. Use a garden hose with lots of water pressure to spray each vent passage carefully to clear lint and dust away. Passages must be cleared in both directions, long ways and cross ways. Cross ways is the problem area and once you finish clearing the air ways you should see daylight through the condenser easily. Reassemble and always clear lint filter in the door /drum area.
My wife has a Bosch Premium dryer that had drying problems. The lint filter would get cleaned but the machine still did not operate correctly, as you explained above. Her machine was made in 2005 and the lint screen, the plastic slotted unit in front of the lint filter was the problem. It gets clogged up with hair/lint that never makes it to the filter. I tried a shop vac to vacuum it but the problem was still there. Get a pistol cleaning kit for a 22 cal gun. Pull the lint filter out & then take the pistol rod and insert it from the drum side into each slot and pull out the tons of lint. Pull the lint off the rod when done and take a flame to burn the rest off as the rod is a brass brush with small wires on it.
i can understand your frustration. i have reviewed the information that i have from Bosch and they indicate that the lint filter indicator light should only come on as a reminder but should not shut off the dryer.
here is my recommendation and also a question:
the dryer is shutting off due to the fact that it's overheating. it's a safety precaution from the manufacturer and it's built in to prevent the lint collected in the lint filter, since it's highly flammable.
check the venting in the back or side, wherever it was installed.
the vent tube is often the cause for the dyer to stop functioning.
if that turns out to be okay, the dyer is equiped with a sensor on the heater. it is possible that it's opening due to the heat generated by the dryer that has nowhere to go.
There is no lint filter in this machine, however, the condensing duct and condensing bellows can get be a problem later on if it gets jammed up with too much lint. If you notice that it takes 50% longer or more to dry your clothes, you will need to have the duct checked and cleared out of excess lint buildup inside. Not an easy job but it can be done.
