Question about Washing Machines

1 Answer

I have a Karcher K3.97 pressure washer. I think I'm losing pressure somewhere because the motor surges on and off every few seconds. No obvious leaks though. Could there be an internal leak through a diaphragm or valve?

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.

I have a whirlpool duet washer and dryer..the washer has a leak... but it's coming from a whole in the outer plastic tub that houses the wash tub right in the plastic..not in a seam or a gasket or where a...


You might be talking about a pressure switch hose connector.
So the way to determine if that is the correct hole:
you have to find the pressure switch and find that slim hose (looks like a fuel delivery on small motors) and follow it all the way down. if it lays on the floor then this is the connection. if the hose you followed connects somewhere then obviously this hole was not meant for it. (only one option)

Is it possible for a water pressure surge to flood a GE Washer?


If you damaged the inlet valve on the machine with water pressure it would surely leak water into the tub even when not in use.If it was a lot of water it may have over filled. That would indicate a pressure switch failure. I would expect to find the hose that goes from the pressure switch to the tub or possibly the pump if it's a front loader, either damaged or disconnected. As a rule pressure switches don't have a high failure rate. So examine the hose first. Let me know what you find.

The washer will no longer do the spin cycle. It makes a grinding type of noise. What might be wrong? How easy is it to take these machines apart? Thanks, Troy


Hi Troy from retired Englishman in France!

We have had a Bosch for 16-20 years (not sure exactly). Brushes wore down a few months ago causing intermittent running and F5 I think. I changed the motor (and belt whilst I was at it) as brush changing is really only a temporary measure- subsequent brushes tend to wear down very quickly. Cost me around £250 but still cheaper than a replacement machine (which is what 'Management' wanted!
Although Bosch washers are very well made and heavy, once the back is accessed the motor and belt are easy to see.
Drum speed is totally controlled by the electronics board feeding the appropriate voltage to the motor- in the same way clockwise and anticlockwise.

If you are reasonably confident [and competent;-0) ] I would suggest removing the back BUT OBVIOUSLY WATCH THAT POWER IS STILL ON and listen whilst it washes then spins.
Question- could there be a metal item sticking through the holes in the drum- or is it really a grinding sound- like a bearing failing? Is the washer old and used enough for something like that?
You should be able to tell by listening with the back off.

Comment: motor and/or belt change- easy; Bearings? I would suggest that depends on your mechanical abilities.
I purchase all my spares for whatever- washer, ride-on mower, Karcher pressure washer etc from the UK via the web.

Good luck,

John C

Error e51 on zanussi iz12


I've had the same problem. I removed the top lit and found some pressure transmitter and a pressure switch. I suspect that the pressure transmitter is use for measuring the waterlevel in the machine. I think the membrane loses its flexibility over the years.
I pulled of the hose from the transmitter and blowed and sucked a few times on the transmitter. After doing this the machine washes without a problem since then.

Hope it helps for you.

My washer does not spin


hi..
there are a few possibilities here,if washer drains water normally that rules out the first most obvious cause of no spin,then it could be the motor brushes-pressing the brushes in towards armature is a rough guide to pointing this direction,also pressure switch pipe(small 10mm pipe) could be blocked thus low level on pressure switch wont be detected,motor control module could also be defective-electrical safety guidlines should always be followed,hope this helps

Karcher Pressure washer


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.

Karcher pressure washer motor surging,then motor cuts out


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.

Water leaking


If it's the hose your talking about, the white tube connected to your tub is called and "air dome" hose. It connects to your pressure switch to shut off your fill valve when selecting load sizes. The hose should connect to a fitting somewhere near the base of the wash tub. If it is leaking, generally mildew inside this tube can cause it slip off it's fitting or lose it's seal. Also the hose can stretch out of shape over time and lose its seal. If you have enough slack in the house, you can pull the hose off the fitting and cut about half an inch off the end, clean the fitting, and reattach. This should reseal it. If the hose itself is leaking, you should replace the entire length of house from the tub to the pressure switch. You can find plastic hose of this type at any hardware store. I hope this helps.
