A foot massager that does not massage repaired.

A woman showed up to my work shop carrying a foot massager and asked me if I can repair such equipment. Usually I do not repair such machines but I was willing to give it a try since my business was a little bit low this week. The machine comes on but there are no massage bubbles coming out from the holes in the bottom of the machine.

It was not hard to open; only few screws and the bottom cover came of exposing all the things inside which were not many. I can see a black part which I came to realize later on that it was the main pump in the unit. That was actually my starting point of the repair. Since there was no massage pressure coming out of the holes that mean the pump is either broken or not getting any power to perform its duties.

The operation of the massager is very easy. 220 volts come from the main electricity outlet to the main switch. As you can see in the photo, the brown wire is the phase. The neutral wire, the blue goes to a different location in the machine. Then it goes directly to the motor that has the fan that has fins which pumps air to push water inside the machine.

The red wire that goes to the motor (in the photo) is the phase and the black wire is the neutral one. Both of these wires should give 220 volts AC but at this stage, no voltage was reaching the motor. As you can see in the photo, there are diodes on the board of the motor. The main job is to convert the 220 AC to 220 DC to operate the motor to pump the air inside the machine. The moment I desoldered the main AC wires from the board, I could read 220 AC on them which is an indication of a bad motor. I tried to spin the fan manually, but it was not spinning very freely. I got a contact solution and spread it on the motor. Now, the fan started to spin very freely. I soldered the wires, turned the machine on and guess what? The motor started spinning. I added water to the machine and I could see massage bubbles coming out.
