WD440G. No heat in wash and dry.

The NTC for the dryer is situated on top of the dryer heater box, fault can often be caused by a simple broken wire, they are very weak at this point.

its the sensor on the dryer

if you take off the top, its mounted on top of the dryer box, usually has a white plug with 2 black wires attached

There is a seperate element for the water heater. so likely to be a faulty heater or thermistor which is fastened toi the element
You really need a test meter to determine which part is faulty.

you need to check Heater element it should read about 32 ohms if ok on a multimeter, next the thermostat should be closed circuit, any loose wires....Hope this helps.

It runs since the motor is still working and turning the drum. No heat since the heater element is broken so no heat got produced to dry clothes. Replace the heater element to correct the problem. Good luck

your heating element or the thermostats that control the heating element could be bad. research no heat for your make of dryer, it should show how to ohm the thermostats and element for fault. They should all read 000 when ohmed. 000 being a complete circuit. I have been having thermal fuse problems with my whirlpool dryer, so I'm learning as I go.

syphon out the water by getting the end of the drain hose into a basin and putting it lower than the water level. a few shakes usually gets it flowing. you probably have a short circuit. my guess would be the heater box/element to start.

you will have a short circuit somewhere. usually the dryer box, but to get the water out you need to put the end of the drain hose lower than the water level into a basin to syphon it out.
the heating element of the dryer sometimes come loose on these machines and can be the cause of a short.

sounds like the heating element of the dryer may have come loose and is shorting against the metal dryer box on top of the drum.
engineer job if you're not electrical

both the 'wash' & the 'dryer' have their own heating elements, If the 'wash' completes its full cycle including 'spin', then I suspect this heat element is ok.Re the dryer, most likely the heat element circuit is 'open circuit' somewhere, could be  the element, thermal fuse, thermostat, or a wire burned out

it is seperate heaters for wash and dry and unlikely to be connected with blocked filter tho you should check filter regularly. take top off. on manifold running across top you will see stats. one of these at least is resettable by presssing a small knob in middle and if it has gone you will hear a slight click. then check dryer manifole for build up of lint as pooir air flow can cause stat to pop. for wash heating, start by checking continuity of the wash heater located at the bottom of the tub
