Check first the filters on the inlet water line. Then, if problem still exist - check that the inlet water valve works(it is an electromagnet valve, located at the pipe's entrance to the machine)). If it doesn't work, test that it get power. In case it get power and doesn't work - You can easily open the valve and clean it (from scale or other dirt). Be aware you should disconnect the power cable from machine before doing it !!!! Check as well for valve's coil resistance. In case you have no resistance measurement - you should replace it for a new one. Good luck

You didn't say if this is a gas or electric machine. I will give suggestions for a gas model. These small engines have air and fuel filters. check both, as it sounds like its getting bad air/fuel mixture. Also try a new spark plug. If this is electric let me know, I'll new some more info.

Hi
don't know if this will help, but when I use mine, to start the pressure up I have to turn the nozzle to fine spray then turn it to the power spray and it works every time, shouldn't have to do this but I got it for nothing.

Dear Sir(s),
The majority of power washers have a spill valve or sometimes called a Control Valve. This spill valve will contract when the gun is closed. As it contracts it switches off a micro switch. Also at the base of the spill valve, an opening opens to let water circulate. Now if this Spill Valve is defective, it will make the machine lose pressure and it will make the machine switch on and off also. I sometimes service the Spill valve and lubricate with special Silicon grease. But if the end of the Spill Valve is not closing correctly, then I suggest that the Spill Valve be renewed. To come to see the Spill Valve, you have to open the cover. Most probably you see wires or a thick wire attached to the head. The part attached to the head contains the micro-switch. Remove the Miro-Switch holder and then you might see screws holding the jammed or faulty spill valve. If you cannot pull the spill valve out, try attaching water and sometimes you can switch on the machine for a second...and with the pressure,...the spill valve will be spitted out.
The switching of ON and OFF due to a faulty Spill Valve, will for sure damage the capacitor. A damaged spill valve gives all these symptoms. Machine going on and off while gun closed and while gun opened, and added to these,... pressure gets less. One small other hint....if all is OK with the machine, and when spraying the machine goes on and off....this is due to a blocked nozzel.
Regards,
Fulltech.

Maytag washer fills with water but dosent do anything else timer does go through cycle i have power at motor but not a nuetral there for motor not running


May not be ur motor it wont run until the water pressure switch signals an ok and starts wash cycle. the pressure switch can be easily checked with a multimeter for continuity on all 3 prongs with should read infinity, u can also do a manual test on it by removing the clear tube that connects to it and blowing into the tube hole or housing on pressure switch. You should hear a click meaning the diaphram is working if no click u have a bad diaphram and faulty switch. Hence no motor running for wash cycle or spin

Maytag model lat 9605 aae fills with water but want agitate or spin out but works fine on delacate cycle thought it was timer put one on still doing the same thing


replace the motor brushes this is common it wont spin or do main cycles but easy go it does is worn brushes
take one and and check the lenght if its less than 50mm replace them
when they get shorter the motor draws more standing current etc running hotter so....
also check the vacume switch and for and rubbish inside the drum skin

Maytag neptune MAH5500BWQ hot water fill runs slow


It is possible that the machine does not start off the cycle because there are errors due to feedback from the inputs. For the program to start up the main program controller must initiate the INLET/MOTOR/DRAIN pump/ valve to open up and allow each function to be driven starting from the flow of water into the drum as also the drain valve to open to exit the water at the point of the program cycle. If this does not happen then the voltage at the valve/motor/pump must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

If the water flows though the inlet then the flow pressure should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.

The on/off switch has stopped working - unable to switch machine on - Plug and fuses checked and OK.


Hi from retired Englishman in SW France,

Sorry but with such a fault it is virtually impossible for anybody on this forum to remotely guess what is wrong with your washer.
It could be internal wiring/plugs sockets, control panel switches, control PCB, water inlet control valves, door solenoid, main motor, drain motor etc..
I fear that your only real option is a service call as the engineer will have the right equipment to safely diagnose what is wrong.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

Washer will not spin or agitate Washer will fil and pump water out motor will not come on Have replaced the motor and the lid switch After replacing the motor the washer worked ok for about 4 or 5...


This is sounding like either a timer or a water level switch problem. I would elimnate the water level switch first. Here is why..... You had to tip the unit to change the motor. Tipping the unit would ensure that the small tube that runs from the bottom (side) of the wash tub to the water level control pressure switch cavitated. Once this is clear the water level control was for a while able to sense proper water levels and the diaphragm inside the pressure switch cycled normally. If the sens line had a pin hole in it or the water level control pressure switch contacts have a problem it will present the symptom you currently have.
I cheat.... I hook up an equal sized tube to the water level pressure switch and add pressure and release pressure orally to force the pressure switch to work. (Automotive vacuum line works like a charm!) If it works by physically forcing it to work then the timer is fine. The Pressure switch is probably ok also. The sense tube running from the presure switch to the tub would be the problem. With all water removed... (drain hose lowered too to empty the machine) tip the unit again. Then see if it will fill and agitate on a small load. Also check to see if it spins. IF it agitates and spins... the sense line if most likely the problem. (pin hole chaffed etc)

There is still a remote possibility of the Timer causing the problem OR the contacts inside the water level pressure switch as the problem. If you can find the tech data sheet inside the console there should be a wiring diagram. Check the water level control for power in and out both with water level reached and empty. If the contacts are working on the water level control pressure switch... your probably looking at the timer as the problem.

Thanks for choosing FixYa,
Kelly

Hotpoint WD64, leaking water from soap drawer


your condenser is blocked,you might be lucky and get away with just cleaning it, but most of the time it is just best to change it. You will have to take the back off again it is the plastic component with the fan motor attached, disconnect the 2 black tubes to it [note where they come from] unscrew the 3 bolts at the bottom , disconnect the wires going to the fan motor. If you are going to change the condensor you will have to take the fan motor off aswell MAKE SURE YOU DISCONNECT THE MACHINE FROM THE MAINS. GOOD LUCK
