william porter, based on your dryer, it looks like you are somewhere in the UK. I do remember that your household voltage is somewhere in the 240Volt range and that your appliance all run on 240V, even the motor sides. Anyhow, as for your dryer, hold the start button in for a few seconds this will reset it. Try it again and see if it will heat then. If not, you may be having trouble with your thermostat. If you have a multimeter, you can check for continuity on it. The other thing you can try is to go into service mode and reset. The way you do it on a drcs68w, so may be it'll work on yours as well. To do this, move to delicate, turn on dryer and keep pressed down cancel button for about ten seconds release then all lights should flash when you press cancel again machine will go through test mode , then just turn machine off. It is now reset. Of course you also want to make sure that there is not obstruction on your dryer vent. Clean it out thoroughly and make sure there are not obstructions. You could try and remove everything from the vent and run it for a few minutes to see if it works. The other thing to try is to measure the heating element for continuity, to ensure it is not fractured. If you find that the heating element is at fault, it is not to expensive and readily available, most of them come with the temperature sensor installed.Hope this helps, good luck.
If this is an electric only dryer I would make sure the fuse or breaker in the main power panel hasn't blown. Remember the heaters use the 220 side and the motors use the 110 side. It could also be the heater coil inside the dryer is dead. Good luck!
"I have a DCX83100W and had the same problem of everything working except no heat. One fine detail is I noticed the dryer didn't begin drying within the usual one second of pressing the Start button. Instead, it paused for maybe 8 seconds, and then began as if everything was normal. Once fixed it went back to starting almost immediately.
SPOILER ALERT * The problem in my case was eventually solved simply by holding the Start button for ten seconds. :-)
But in case you aren't so lucky, before I found this post (many thanks @oldturkey03 ) I tried many things and here's some detail in case it helps you track it down:
I tried to reset the thermal fuse (black button) built into the heater behind the guitar-shaped rear panel with a zillion screws, but it hadn't popped-out.Checked the resistance of the two heater elements - 37 Ohms and about 70 Ohms.Checked the resistance of the front thermostat, “NTC” (shiny metal pipe sticking into the airway below the door where the lint filter lives) - about 1kOhms at room temperature.Checked the moisture sensor wiring was connected (two curved metal strips inside the drum, under the door, wired to the front panel by a pair of thin orange wires on a six pin connector shared with the thermostat).I found a blown up triac on the main circuit board and replaced it, but it was just the one that powered the courtesy light, whose bulb had blown, and fixing it didn't solve the heating problem (although I do wonder if its failure maybe led to the machine needing a reset in the first place).I eventually checked the live circuit board to confirm that the relays and drive transistors for the two heater elements were ok, and the microcontroller was never energising them. When I realised this and knew I'd already confirmed that all the other sensors were all working, I realised I had either a controller fault or needed a reset somehow, and then thankfully found this post. Resetting by pressing the Start button for ten seconds seems to have solved it and the dryer has now worked for several loads without a hitch.**** Obviously this is a mains appliance and it contains potentially lethal voltages when powered. Take appropriate precautions, and if you don't know what you're doing you should find someone who does. ****"
