I fixed it! - IN SHORT: REPLACE THE HEATER AT THE BACK. IT’S EASY!

I had the same problem recently.
Whenever you search for it, it shows the error code E21 result of another dryer.

I even asked an expert from a particular website and they suggested it means water left in condenser or condenser pump not responding. - NOPE this is again the same as the google search I conducted myself which was useless.

I figured that if the heater isn’t working I’d have a look at it. Took off the screws at the back around the centre surround and then two screws for the heater and pull the plug out which is behind the rubber where the wire goes into the dryer.

Replace with replacement heater and it works.

USE A PROPER GUIDE

I got mine from RansomSpares £34.95 part number RS741100

Hi

E21 is to do with the heater. There’s a thermostat on the heater that’s shuts all the heat off the machine if it gets to hot. (Safety feature) you just need to replace the thermostat on the heater and your all good to go.

Had the same error message. Tried the thermostat first, it definitely wasn’t the issue. When I opened up the heater I noticed the wire where it connects to the heating element, had corroded away. Instead of spending money twice just go for the heater replacement. It works.

Can anyone send a link to the spares they bought, and any ideas on how I can fix it I’ve got a new baby and our dryers packed in with this message
I can’t seem to figure it out. TIA

Hi there
Is it expensive and or difficult to replace heater ?
