Bosch builtin 60cm SGV4313 dishwasher

the pump controller or pump switch over is defective, basically your power module is faulty and unable to power the pump, you will need to replace the power module

Run away. It is not a do-it-yourself project, as these machines are complicated beyond normal reason... Call a technician, trust me.

It could be the floating switch that is jammed leading the machine to think that there is water in it or it could be your pcb.

Good job Bosch,, just kept their quality of support. In the future you can always check on the float switch.

Hello Zub,

It's most likely a fault with the control module or the drain pump. Please follow these instructions to detemine the likely cause of the fault and, therefore, what to do next:

1. Turn the programme selector to any wash cycle but don't press start.
2. Open the door and pull out the lower rack
3. If the washer is dry, pour roughly a pint of water into the sump in the bottom of the washer
4. Locate the float (the mushroom) and lift it . . .


When the float is fully lifted (about 3/4 of an inch) the drain pump should start and drain any water from the washer. This activates the anti-flood safety feature and the pump should continue to run as long as the float is lifted. The power supply to the drain pump bypasses the controller so this is the best way to determine if the drain pump is faulty.

If the water drains when you lift the float . . .

The drain pump is working but it's not receiving the signal to start from the controller during a wash cycle. It may be a wiring problem, but more likely that your control module will likely need to be repaired or replaced. These cost about £100 - if you replace it yourself.

If you can hear the pump humming but water does not drain when you lift the float . . .

There may be a blockage somewhere or the pump impeller may have jammed or broken away from the driveshaft. Try lifting and dropping the float rapidly about 10-20 times. Repeated stop/start signals to the pump motor can free a stuck impeller.

If nothing happens when you lift the float . . .

There is either no power to the pump motor or, more likely, the pump motor has failed. You will need to test the motor to determine whether or not it needs to be replaced. You will need a Torx T20 screwdriver or screwdriver bit to remove the kickplate under the door and an ohm / multi-meter to test the motor.

The drain pump motor should give a resistance reading of between 110 and 260 ohms across the live/hot and neutral/common terminals if the motor is good. In most cases, the reading is about 160-170 ohms.

I'd suggest testing the drain pump using the float as detailed above, then let me know the results. I'm happy to provide further assistance once the likely cause of the fault has been determined.

Hope this helps.

Where does the clicking sound seem to be coming from? Start the machine and when it's filled with water, try to identify where the clicking noise is emanating from. I suggest putting you ear next to the programme selector and start/stop switch and see if you can hear it more loudly/clearly.

Sounds like a faulty control module to me. Try the above and report back . . .

you have a bad control module. send me a 4 thumbs post if this was helpful to you.p.s im a old bosch tech

Obviously a faulty connection. Lots of switching off and on and holding down the buttons eventually sorted it!

Mine was doing exactly the same. I turned off power, held down the 2 black buttons on right, switched back on and the start button flashes intermittently. It then allowed me to change programs, just testing it now!! It started, this was more then it was doing!! lol
