Question about Hotpoint Aquarius WD640 Front Load Washer/Dryer
Hi. We have a hotpoint washer dryer aquarius wd64 model and cannot get the dryer to work. We have tried everything we csn think of and still our clothes stay wet! Please can you help? Thanks.
REMEMBER: when checking the resistance ensure that all wiring is disconnected from testing points!
Remove the top cover of the washing machine, you'll see about a foot size aluminum casing of the heater itself. Using a multimeter set on resistance (ohms) check the resistance between two welded pins (heating element) The readings should be roughly fom 0 to 26 ohms. If there's no readings you'll need to replace heating element, othervise check the resistance of thermo-fuse wich is located between those two welded heater pins. one of the wires connects heating element and thermo-fuse directly. The readings should be around 0 ohms, if no reading just replace the thermo-fuse.
Lets end at this point for now, as replacements thermo fuse solves the problem in most cases.
Please update me about your success, If unfortunately it didn't helped, just say and we'll find the solution!

With both the WD 64 & a previous model, I have found that fibres from fabrics build up in the plastic duct that takes the hot air from the heater box (above the drum) and the point where it enters the back of the drum. On our present machine it was so bad that barely any air flow was getting through. This will eventually cause overheating and a thermal 'trip'. The only solution is to competely remove the duct section and clean it out. After disconnecting power, remove the top and back covers of the machine. Working from the top, remove two self-tapping style screws that attach the duct to the heater box, then working from the back, remove three hexagon headed machine screws (8mm AF I think) that hold the lower end of the duct in place by retaining clips. You will also need to disconnect cables from the fan motor (slide off spade connections) and a couple of small bore rubber hoses. You should then be able to withdraw the duct and fan as a unit, out the back of the machine. Watch out for the 'O' ring on the lower end. You then need to remove the complete blower fan unit from the duct (3 hex headed machine screws). With this removed you can access the inside of the duct and rod it out with something appropriate. In our case the fan impeller was completely coated in a thick layer of what looked like grey felt, rendering it virtualy ineffectual. The duct itself was also thickly lined, I had to use a long wooden skewer to poke the felt out of all the passages.
Once the cleaning is done, reassemble, taking care to refit the 'O' ring on the lower end of the duct. Also ensure that when the duct is reinstalled, there is clearance between the drum and the little black cooling fan on the back of the blower motor, otherwise it will clatter against the drum and impede the blower action.
I removed in total a large heaped cereal bowl of 'felt' from the duct and impeller, and dryer performance went up by 99%.
