Question about Bosch Washing Machines

1 Answer

I have a bosch aquatak 1300si which no longer switches on. I've tried changing the fuse, unplugging the hoses and reattaching. I can't see any physical damage of the machine or power cables.

Switch Control unit, having Stop, Play, FF, Rew, Pause and Tele-Wide switch at top of camera is cause of this problem. Its ribbon wire has been damaged / cracked, going to camera board. You need to replace that complete part because ribbon wire is not available individualy.

Since this machine is only sold in the UK I do not have a picture to point you to.
The problem is probably a blown thermal fuse. This fuse is located inside the machine and is for detecting overheating and fires. Sometimes age will cause it to fail. It's generally located near the air vent outlet.
If you handy with fixing gadgets you can check it.
Unplug the machine and remove the cover.
You can take an ohmmeter and test it. If it shows open you can replace it. It may be soldered in I am not sure. You can get replacements at an appliance parts store or Radio Shack®. There may be conventional fuses inside so you can check them also.

If nothing else is wrong it might be a door switch problem.
Wear on the interlock causing the crowbar microswitch to short the line and blow
the internal line fuse. The interlock, required by law, contains 3
switches - one switch sends a door-open signal to the
microprocessor, one opens the line and the third crowbars (shorts)
the power leads to the magnetron. If the crowbar switch activates
before the line switch opens, the line fuse gets blown. Just toss the crowbar switch.

What your amp is doing is going into protection mode. The Class D amplifier topology uses a Pulse width modulation scheme which allows the audio to be modulated onto a generated square wave or pulse train. This is then sent through the MOSFET Driver and then to the High Power MOSFETs that drive the load. The square wave with modulated audio is then filtered by a low pass filter and you are left with your audio. This is great because of the very high efficiency. The downside is that there are more links in the chain to fail. In your case it sounds like one or both of your power MOSFETs are bad and are causing the watchdog circuit to send a shutdown signal to the switching power supply, this is why it is turning off. It is a safety feature to prevent catastrophic failure of the board. (ie. burning the PCB to a crisp) A technician experienced in PCB level troubleshooting shoot be able to repair this for you. Let me know if you need anything good luck.

Bosch aquatak power washer will not start

Check to make sure the outlet (power supply) is energized. This piece of equipment is supposed to be used on a ground-fault protected circuit, so make sure the ground-fault on the outlet didn't trip or the circuit breaker (fuse) at the electric panel did not trip (or blow)
Check to make sure you are going through the proper starting procedures as outlined in your user's manual on page 8.
Follow the troubleshooting tips on page 10 of the user's manual.
Beyond that, Bosch requires that you have your power washer repaired at an authorized / qualified repair center.
I did locate a web site that shows an exploded parts view of the pressure washer, if that helps.
In case you don't have a user's manual, you can view it at:
Best wishes on your project.
