Runs with no heat
The drum turns and the timer moves, but clothes come out cold and damp.
Start here: Start with the lint screen, exhaust hose, and outside vent hood. If airflow is good, move to the heating parts checks.
Dryer error code
Bosch Dryer E06 Code
Direct answer: A Bosch dryer E06 code usually shows up when the dryer is not heating normally or airflow is restricted enough that the machine stops the cycle to protect itself.
Most likely: The most likely cause is a packed lint screen, clogged vent path, or crushed exhaust hose causing poor airflow and overheating.
Start with the easy outside checks: lint screen, exhaust hose, and the vent outlet where the dryer blows outside. If airflow is weak or the dryer gets hot but clothes stay damp, fix the vent issue first. Reality check: a lot of E06 calls end up being a vent problem, not a bad main board. Common wrong move: replacing heat parts before clearing a half-blocked vent just burns up the new part again.
Don’t start with: Do not start by ordering a dryer control board. On this code, airflow and heat-safety parts are far more common than an electronic failure.
If the dryer runs but does not heatCheck airflow and the vent path before opening the cabinet.
If the code comes back right after a resetSuspect a real heat or sensor problem, not a one-time glitch.

What E06 usually looks like in the real world
Heats briefly then throws E06
The dryer starts normally, warms up for a short time, then stops the cycle or posts the code.
Start here: This pattern leans toward restricted airflow or a heat-safety cutoff opening under load.
Very long dry times before the code
Loads eventually dry, but only after extra cycles, and the cabinet may feel hotter than normal.
Start here: Treat this as an airflow problem first until proven otherwise.
Code returns immediately after clearing
You reset the dryer, restart it, and the code comes back quickly even with an empty drum.
Start here: Once airflow checks are clean, look harder at the dryer heating element, dryer high-limit thermostat, or dryer thermal cutoff.
Most likely causes
1. Blocked dryer vent path
This is the most common reason for heat-related dryer faults. The heater runs too hot, airflow drops, and the dryer protects itself.
Quick check: Pull the dryer forward, disconnect the exhaust hose, and check for a heavy lint mat, crushed flex hose, or weak air at the outside hood.
2. Packed lint screen or lint housing restriction
A lint screen coated with softener residue or a lint chute packed below the screen can cut airflow more than people expect.
Quick check: Wash the dryer lint screen with warm water and mild soap, let it dry, and look down into the lint slot with a flashlight for buildup.
3. Open dryer thermal cutoff or dryer high-limit thermostat
If the dryer overheated from poor airflow, one of the heat-safety parts may have opened and left you with a no-heat condition and recurring code.
Quick check: After airflow is confirmed good, continuity testing of the heat-safety parts is the next solid check.
4. Failed dryer heating element
A broken heating element can leave the dryer running with little or no heat, and some machines will flag that as a heating fault.
Quick check: If airflow is strong and the safety parts test good, inspect and test the dryer heating element for an open circuit or visible break.
Step-by-step fix
Step 1: Clear the easy airflow restrictions first
Most E06 complaints are caused by poor airflow, and this is the safest place to start.
- Unplug the dryer before moving it.
- Remove the dryer lint screen and wash it with warm water and mild soap if it feels waxy or looks coated.
- Vacuum loose lint from the lint screen opening if you can reach it without forcing tools into the machine.
- Pull the dryer out and inspect the exhaust hose for kinks, crushing, or a heavy lint clog.
- Go outside and make sure the vent hood flap opens freely and is not packed with lint, nests, or damp debris.
Next move: If you find a blockage, clear it, reconnect the vent, and run a short heated cycle. If the code stays gone, the problem was airflow. If the vent path is clear and the code returns, keep going. You have likely moved past the simple restriction checks.
What to conclude: A dryer that cannot move air will overheat internally even when the drum still turns normally.
Stop if:
- You smell burning lint or melting plastic.
- The exhaust hose is damaged badly enough that it cannot be reconnected safely.
- The outside vent path disappears into a concealed wall run you cannot inspect.
Step 2: Separate a vent problem from a dryer problem
This quick test tells you whether the restriction is in the house vent or inside the dryer itself.
- With the dryer still pulled out, disconnect the exhaust hose from the back of the dryer.
- Reconnect power.
- Run the dryer on a heat setting for a few minutes with no clothes in it and with the hose still off.
- Feel for a strong blast of warm air at the dryer outlet.
- Watch whether the E06 code returns during this short test.
Next move: If airflow is strong and the dryer heats normally with the hose off, the house vent is the problem. If airflow is still weak or the code returns even with the hose removed, the issue is inside the dryer.
What to conclude: Good performance with the vent disconnected points away from internal parts and toward a blocked vent run.
Step 3: Reset the dryer once after airflow is corrected
Some dryers will hold a heat fault until power is cycled, even after the original restriction is fixed.
- Turn the dryer off.
- Unplug it for a few minutes.
- Reconnect power and start a timed heated cycle with an empty drum.
- Watch for normal heat, normal airflow, and whether the code stays away through the first several minutes.
Next move: If the dryer heats and the code does not return, finish by cleaning the full vent run before putting the dryer back in place. If E06 comes back quickly after a clean vent and reset, move on to internal heat-part checks.
Step 4: Check the heat-safety parts before the heater
On a dryer that overheated, the dryer thermal cutoff or dryer high-limit thermostat often fails before the heating element does.
- Unplug the dryer.
- Open the access area needed to reach the heater housing and thermostats.
- Locate the dryer thermal cutoff and dryer high-limit thermostat on or near the heater housing.
- Test each part for continuity with a multimeter after the wires are removed from the terminals.
- Inspect the terminals for heat damage, loose fit, or discoloration.
Next move: If one of these parts tests open while airflow is now confirmed good, replace the failed heat-safety part and correct any vent issue before running the dryer hard again. If both safety parts test good, the heating element becomes the next likely internal failure.
Step 5: Test the dryer heating element and decide the repair
Once airflow and safety parts are ruled out, the heating element is the strongest remaining no-heat cause on this code path.
- With power still disconnected, inspect the dryer heating element for a visible break, burnt spot, or coil touching the housing.
- Test the dryer heating element for continuity.
- If the element is open, replace the dryer heating element.
- If the element tests good and the safety parts test good, stop here and schedule appliance service for deeper diagnosis of wiring, sensors, or controls.
- After any repair, reassemble the dryer, reconnect the vent without crushing it, and run a heated test cycle.
A good result: If the dryer heats normally, airflow is strong, and E06 stays gone, the repair path is confirmed.
If not: If the code still returns after verified airflow and good heater-circuit parts, the problem is beyond the usual homeowner repair path.
What to conclude: At this point you have ruled out the common field failures and should avoid guessing at expensive electronics.

FAQ
What does E06 mean on a Bosch dryer?
In practical terms, E06 usually points to a heating or airflow problem. The dryer is not seeing normal heat conditions, often because the vent is restricted or a heat-safety part has opened.
Can a clogged vent really cause an E06 code?
Yes. A clogged vent is one of the most common real-world causes. The dryer cannot move enough air, internal temperatures climb, and the machine shuts the heat down or posts a fault.
Should I replace the heating element first for E06?
Usually no. Start with airflow, then test the dryer thermal cutoff and dryer high-limit thermostat. Replacing the heating element first is a common way to spend money without fixing the cause.
Will unplugging the dryer clear the code for good?
It may clear the display temporarily, but it will not fix a blocked vent or failed heat part. If the cause is still there, the code usually comes back quickly.
Can I keep using the dryer with an E06 code?
It is better not to. A dryer that is overheating, not venting well, or shutting down on a heat fault can damage parts and create a lint-fire risk if you keep pushing it.
What if airflow is good and the heater parts test good?
At that point, stop guessing. The problem may be in wiring, a sensor, or the control side of the heater circuit. That is where a service tech with the wiring information and live test procedure earns the money.
