Where can I get a replacement motor for a Fubbles No-Spill Bubble Machine?
The machine stopped working. Replaced batteries. Took apart and connected power wires. Took further apart and saw motor was burnt out (probably from getting bubble mixture inside). If I can find a cheap replacement motor I think I can get it working again. Motor is a small electric motor, a 1 inch long cylinder about 3/4inch in diameter with a small fan attached at one end (just under 1.25inches in diameter) with a cylindrical spiral gear shaft on the other end.

Dear Sir, The motor is humming, because as you noticed, the capacitor is faulty. To change the capacitor, one has to open the machine, by removing the covers. Usually a screw driver TORX T15 is used. The capacitor is very easy to locate and with a little knowledge it can be replaced. Now the BIG PROBLEM...is WHY, the capacitor got faulty. In many cases the valve that controls the pressure and shuts off and on the machine...called the SPILL VALVE...is faulty. If this is so, the machine starts going on and off...then the capacitor gets damaged. So this spill valve and maybe intake and suction valves must be replaced. One can try the machine with a new capacitor and observe what happens. Jerking machine...means Spill Valve damage and/or suction and delivery valves damage.
Normally when one closes the gun the machine stops. So you may have a blockage problem that is shutting the machine off. You may try to diusconnect the gun so that you run the machine without load. But..ALWAYS...with water being fed. Never run a power washer without water being fed. Without gun and water fed normally....your machine should continue working. If so you can attach the gun without the lance. If it works, you have a blocked nozzle in the lance. If so try with a very thin needle to clear the nozzel. Do not make the nozzel's hole bigger with cleaning, because then you lose power. Now these machines stop automatically by means of a control valve (Spill Valve). The spill valve when the gun is closed, pressure is created and the spill valve in turn will move to close the electricity by means of a micro switch. Spill valves give a lot of trouble if machine is left with soap in it, or if the machine is stored with pressure in it. NEVER STORE A POWER WASHER WITH PRESSURE IN IT.....always when finished working disconnect electricity, disconnect water and finally press the gun to release pressure. Well as I already said start by putting on machine without load. Then add the gun without lance so that you see that when you close the gun the machine stops....and when you open the gun machine starts again. All this without lance attached. Also in cases like these the Spill Valve sometimes gets jammed in the cutting off electricity position. Spill valves only need to be serviced with good silicon grease....but in doubt change the spill valve. If you open the machine the spill valve is located where you see 2 wires coming out. You should have special tools to remove and service/change the spill valve. Well hope you have a small idea from where to start.
When the trigger is released, pressure builds up and this acts on a valve (spill valve or pressure control valve). When this pressure is big enough it will push the spill valve out and closes a micro switch. Now this Spill Valve gets stuck sometimes, mainly due to soap and chemicals...so the micro switch is not closed...so the machine contiues running. If this is left likee this it will cause damage to the valves. So all one has to do is service the spill valve or as I usually do I replace it. There are cases were the micro switch is damaged also..and needs to be replaced. To see the spill valve and micro switch you must open the cover. The spill valve is located where you see a cover with an electric wire coming out of it. If the micro switch is good...you must tackle the Spill valve.
I own a Saeco Incanto Deluxe. It employs the ceramic grinder that has worked flawlessly for 3-4 years. One day it stopped and "Grinder Blocked" appeared. I removed the entire grinder unit, cleaned it thoroughly and calibrated the grinder. This did not fix the problem. After many similar attempts, I found the entire grinder assembly (motor, grinder etc.) online for $149.00. Install of the new assembly took me five minutes and it works perfectly. Please note that the ceramic grinding blades (there are two round ones that must be aligned corrrectly) cost $40 a piece (same site where I found the entire assembly for $149). My suggestion--save yourself the agony and replace the assembly if cleaning and calibration fails.
There is a valve called the spill-valve. It is often called the control valve. This valve activates the micro-switch. When the gun is released, pressure builds up and compresses this spill valve. At the same time it puts off the micro-switch. This will then stop the machine. Now when the spill valve is faulty it cannot hold compreesion under pressure so it starts de-compressing and starts the machine again. This goes on in a cycle as you explained. So you have to change the spill valve. If the spill valve that operates the micro-switch is part of the upper head,...then the whole head must be renewed. Myself I rarely service Spill Valves. The best thing is to renew it. From your explanation it seems that you did not take notice of this Spill-Valve. Infact when you mentioned Pressure Switch, I do not know if you are refering to the spill valve. If you are....then saying that the Pressure Switch moves and operates freely, does not mean that it is OK.
In certain machines in the outlet...there is a small valve, coloured black and red or green and yellow. This sometimes when faulty, it gives the fault you mentioned. Sometimes an inlet valve gives the fault you mentioned. But from my expirience it is most of the time that the Spill-Valve is the fault.
When trigger is shut, pressure builds up in machine and this activates a control-valve or often called a Spill Valve. This Spill Valve compresses with the built up pressure and switches off a micro-switch...which in turn stops the machine. Now when this Spill Valve gets faulty, it starts compressing and de-compressing undr pressure. Thus the micro switch is activated on and off. That is why your machine is starting and stopping. Now this Spill Valve also controls pressure. So to fix the fault you must change the Spill Valve with a new one. Myself I rarely service Spill Valves. You can locate the spill valve after you open the cover. The spill valve is usually covered with a plastic cap that contains the electrical micro switch. I do not know what model you have....but sometimes to improve the pressure you must also change the suction and delivery valves. But in most cases like yours...it is only the Spill Valve that is causing the starting and stopping and the low pressure.
Dear Tigger82 (also montaver2000),
This explaination is relavent to various Karcher models, especialy your model. When you are using the machine with the gun open....presurised water comes out of the lance. When you close the gun, the machine stops. This happens by means of a Spill Valve or often called the Control Valve. When the gun is closed, this spill valve cotracts with built up pressure and at the same time works on a miro switch which cuts the electricity....and thus stops the electric motor. Now in many cases when the gun is again opened, this spill valve sticks and keeps the electric circuit closed.
In all cases you must open the cover, and locate this spill valve. Sometimes it is easy to see a micro switch on it. If you remove the miro switch from the spill valve the motor will for sure turn.
Now the spill valve gets stuck for many reasons. One of the reasons is that you leave the machine under pressure for a long time and even store away the machine with pressure still in the system. A spill valve also gets stuck due to detergent. I sometimes service the spill valve and lubricate with special solicon grease. But the best way is to change the spill valve with a new one. So in a few words, the spill valve is stuck and leaving the microswitch off. So the electric motor cannot turn. One final hint is that sometimes the spill valve is difficult to remove. So all one has to do is attach water supply and switch on the pump. With the pressure produced the spill valve will be pushed out. In my oponion this job must be done by a person who knows what he is doing. Carefull that you have safety electrical breakers. See that you have safety shoes, safety gloves and eye protection.
My mah6700aww would get to 9 minutes then stop, water would not evacuate. I took the exhaust pump/motor apart and found a piece of plastic (foreign debris) in the impeller; remove the obstruction and re-installed the pump/motor; problem solved. Three bolts that hold the pump/motor in place are 12mm. Also, important to mark the top of the plastic female electrical power connection since it is possible to reverse the connection. I saved $350 min. if you do need to replace the pump/motor they cost about $150 at an appliance parts store. Good luck, Ed
that is your only solution but u might find u can buy a second hand machine that works for u to get parts off this will proberly be cheaper than buying a timer thats what id do u get more for your money m8
