Question about Hotpoint WMA64 Front Load Washer

Hotpoint WMA64 Won't heat up

WMA64 won't heat up the water. I have used a multimeter on the Element and it appears to be okay. One suggestion that I saw suggested there might be something burnt out on the circuit board but, I have checked and there is nothing obvious there. Other posts suggest it may be the Thermostat or Thermistor. What is a Thermistor and what does it do? Also any idea where these components are located and what they look like ? Any help appreciated

    Hi I checked the Heater element again and it showed a resitance so still okay. I then checked the heat sensor connections on the heating element and this showed nothing but, this could still be okay depending on the kind of device it is. Lastly I followed a clear tube from the water outlet to what could only be the Thermostat. I took off all wires and checked for continuity and they all were okay so I put it all back together again. When I switched the washer on it started heating up ! I suppose it was just a bad connection somewhere. Thanks for your help, Paul

Thermistor is resistance which changes in value when it is hot. So this acts as a thermocouple.
In this case it is possible that the power control has failed from the board, it can be due to damaged connectors or links. Use a meter to test the continuity.

    Hi thanks for the quick reply. I'll check the wiring again. The heater worked for a short time when I removed and reconnected the wiring again. Am I correct in saying that the Thermostat is connected through the heating element and has a small plastic connector? thanks Paul

SOURCE: Hotpoint Aquarius Washer dryer WD64 Not Heating Wash Water

hi pw82,

its seems you're doing your home work. that cylindrical part is the thermostat itself. it should have a resistance in the range of kilo ohms. around 10 kohm to 25 kohms. you can try to change the range of your testing equipment so that you could be sure that te thermostat is really open circuit.

if there is no resistance, then that is the problem. if there is resitance in the kilo ohms range then it could still be ok and you need todo some further testing.

you can check for voltage presence at the terminlas of the heater. if there is no voltage then it could be the relay on the power board that supply voltage to the heater.
or the board itself.

i hope i was able to help..please rate me..tnx

SOURCE: washing m/c water not heating up.

Make sure the economy button is not selected if it has one, as this bypasses the heater..
you say you have had element checked and seems o/k, to be certain it is o/k then test with a meter when it is on heat stage in the prog, and make sure you have a 240V reading across the heater terminals, if you have and it does not heat, then the element is faulty.
Plz rate my solution.
Thanks.

SOURCE: my hotpoint wma31 won't start,

It's a good machine. Well done for keeping it that long. It sounds like maybe it thinks the door is still open. (What happens if you intentionally try to start the program with the door open - It the result exactly the same? If it is, then it's probably the door interlock sensor.

If this is the case then you may find that a couple of good slams of the door will free off anything taht is sticking. Otherwise, you may have to check to see if there is a wire off the sensor (They do fall off sometimes) or.. after 13 years, it may need a new door sensor

Bosch SGVE53E13GB Integrated dishwasher- cycles but won't finish


The heating element in the bottom of the unit may be burned out. With an ohm meter, check to see if there is any resistance with power removed and terminals of heating element exposed. If it measures about 1 or 2 ohms, it is okay. Anything more than about 200 ohms means there is likely a break in the element., If it is okay, then check the wiring to the heating element.

I have intermittent problem with two of the four rings - sometimes they work sometimes they don't


see this causes and proceed for fix it. God bless you
Surface Element Switch If the surface element won't work, and there is another element of the same size on the stove, try switching the elements. If it still won't work, the surface element switch is probably defective. The surface element switch can't be tested or repaired, it will have to be replaced.

Surface Element Board If a surface element won't work the surface element board might be defective. Each burner is switched on and off with the help of a relay on the surface element board. If one or more relays has failed the surface element won't work. If two or more burners fail at the same time, this is likely the problem. If only one surface element won't work and the element itself checks out to be good, the surface element board might be defective.

Coil Surface Element If the surface element won't work, the coil surface element might be burned out. Most coil surface elements can be pulled out of their socket and checked with an Ohm meter for continuity. If the surface element won't work, check to see if there is any visible damage to the coils. Also, check to be sure the element is pushed all the way into the socket.

Radiant Surface Element The most common cause when the surface element won't work is the radiant surface element itself. The radiant surface element - or heating element - can burn out similar to a light bulb. If the surface element won't work and it doesn't have continuity, it will need to be replaced. The radiant surface element is not repairable.

Solid Surface Element If the surface element won't work, and the stove has the solid surface element type of heat, it's likely that the solid surface element itself has burned out. The solid surface element works very similarly to other surface elements - inside there is a heating element that glows when electricity is applied to it. As it gets hotter, the heat is transferred to the solid surface element

Terminal Block If a surface element won't work, there may be a problem at the terminal block. The appliance has a power cord which is attached to a terminal block. Over time, the connections at the terminal block can fail and burn open. When this happens, normally all of the surface elements won't work. The solution is to replace any burned wires and replace the terminal block.

Loose or Burnt Wire Connection If surface element won't work, there might be a burnt wire supplying power to the surface element. Sometimes the wire supplying power to the element burns out right near the element itself. Check for this by just looking at the wires leading to the element. If they're burned out it is usually easy to spot.
Incoming Power Problem Although not as common, if the surface element won't work it is possible that the appliance is not receiving proper voltage. Electric ranges require 220 volts of alternating current. If for some reason the appliance is receiving significantly less, the surface element won't work. Check for proper voltage using a volt meter at the socket where the appliance plugs in.

Hotpoint oven won't heat above 250 degrees broiler works fine as well as the stove top


either its the oven sensor rod located at the top of the ovens cavity,or your bake element could be getting a hot spot which is when it gets a discolored spot in the element and can no longer pass sufficient current to heat the oven past 250 degrees

Miele wt945 won't heat when washing


Possible that the heating element is faulty. It is best to confirm using a multimeter to test the continuity of the element. If so then check the voltage on the element at the time of the cycle and if there is no voltage then the controller unit is faulty. check for fault in the connectors , wires or links.

I have a Westinghouse SB915SJ*00 dishwasher. It runs right through a cycle but does not heat. Any suggestions? Thanks.


Hello

The majority of dishwashers are not connected to hot water from the mains but heat up the water internally using the heating element, located in the tub of the dishwasher, controlled by a thermostat. When the dishwasher has a fault with heating, the program will run but not complete and will show an error code on the display panel. Dishes won't be cleaned properly and the detergent won't dissolve.

If your dishwasher does bring in hot water externally from the mains to check the water is warm and there are no problems with the inlet. If the dishwasher heats internally then it is most likely a faulty heating element or thermostat. A fault like this will usually require a replacement part and a repair, but you can check the heating element with a voltmeter to ensure that it is the cause of the problem before calling out for a service engineer.

I have a fisher & Paykel electric dryer. D-DE62T27D that works but won't dry. Any solutions? Thanks Rick


Disconnect the power source to your dryer before you conduct this or any other test. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.

Dryer heating elements come in various shapes and sizes. They are all strung with a coiled wire made of a nickel and a chrome alloy. This wire receives, but resists, a controlled electric current and as a result, the wire heats up. The heat produced is used to heat and dry the clothes in your dryer.
Once you have gained access to your dryer's heating element, set your multimeter to the R x 1 resistance scale. Touch each meter probe and to one end of the element. If you receive a reading of infinite resistance, then your heating element is no longer functioning properly and you will have to replace it.

When using the oven the electicity tripped; after resetting the breaker the oven does not appear to get hot; however the grill works, the light works and the fan works what could be the problem?


Sounds like the oven element has gone. When these elements go they often short against the outside casing of the element which is earthed (or should be). This trips the main trip switch in the house. Having tripped and cooled down, the element is now broken inside & won't heat up. Usually 2 screws to remove, either inside oven or outside at back. Element usually taken out thro oven. Take it & cooker info to your dealer & ask for replacement. Shouldn't cost much.
