Question about Dryers
HI sorry to have to ask again but the previous post seams locked to me. I have a dryer as stated above with an error that is not listed in the manual. When you turn the dial to select a programme the start led begins flashing and will let you start but regardless of starting a programme or not the machine appears to go through a self-check procedure. Shortly after you turn the dial to select a programme an error of 3 beeps and the level 1 and 3 elements Leds of dryer level begin flashing. Could someone confirm what the error is? thank you. Having been an electrical engineer in manufacturing for a long time my guess would indicate a heater element fault but would a heat pump version even have a heating element.
I think it is a play on words and heat pump means it pumps heat. A heat pump in normal parlance is taking heat from a source that would be wasted, like turning a refrigeration system around and using the heat supplied from cooling, to heat an area.
I would guess it has an element, and when you look at the wider view, it is a condensing dryer so the heat from the element makes steam from the clothes which is condensed by the incoming cold air, ergo, it is a heat pump.
Get your old multimeter and screwdriver out and start testing.

Testimonial: "Hi Thanks for the reply, in the mean time I had being just that, wasn't able to fault any of the components but in the mean time Ive managed to clear the fault and its working okay now (maybe I disturbed a loose or poor connection along the way. From the internet - What is a heat pump tumble dryer? A heat pump tumble dryer absorbs the water from your laundry by passing hot air through the drum. This air then goes through an evaporator which removes the water and stores it in the tumble dryers’ reservoir. This air is then reheated and sent back through the drum multiple times until your laundry is dry. Also for those who want a video description of how these dryers work without a heat element (uses a condenser). https://www.youtube.com/watch?v=IWqNmOLHwt0 This works considerably different to vented and condenser tumble dryers, as in both instances they do not take advantage of the air they have already warmed. Heat pump tumble dryers will use considerably less energy, as they are reheating the same air, which is already warm from the previous cycle."
