Re: Bosch SGV57T03GB wash times extend to 144min

A final update……

Cleaning the hose at the front of the machine did not sort the problem. I carried on with the extended wash times, but then one day the machine didn’t wash at all. The cycle ran, but no water entered the machine, and the drain pump kept running.

Investigations revealed that the sump pan underneath the machine had water in it. This was raising the float, and causing the pump to run constantly.

Draining the sump (using a tube and the ‘suck’ method – not pleasant…) allowed the machine to work again, however a small stream of water was observed from the area of the sensor mentioned earlier in the post, when the machine was filling. After about a week, the sump was again flooded.

Something had to be done, so I resolved to try cleaning the sensor. This I succeded at, which resolved all the problems. The sensor was so clogged that it was leaking as it tried to fill the machine.

Anyway, here is the process I used……

1. Turn off the Water and Electric to the machine (!)

2. Remove the door of the machine – see earlier.

3. Unscrew the machine from the work-surface – there are two L shaped plates attached to the Front LH and RH top edges of the machine. These are push-fit into the top of the mashine, and either screwed to the underside of the worktop, or to the neighboring units. It may be that it is impossible to reach the fixing screws if the unit has been fitted whilst the kitchen is being built, however this is not a problem, as the machine can be dropped down on it’s screw legs, and the plates popped out from the top of the machine with a screw driver. In refitting the machine, I didn’t bother re-fitting the plates.

3. Pull the machine completely out, so that the rear of the machine is accessible. A number of steps below require access to the rear.

4. Undo the two screws on the front of the machine holding the LH side panel (mentioned in an earlier entry)

5. The side panel wraps around the back of the machine slightly, and is located on a white plastic pin at the rear of the machine. It must be pulled away from this pin before the side panel can be pulled away from the machine – it ‘hinges’ on its bottom edge.

6. The machine should now look like the photo earlier in the thread entitled “Here is the whole side off” -however there will be restraining bars across the matrix.

7. Remove the restraining bars.

8. Remove the two white plastic corners (top left and top right of the picture) holding the Matrix onto the machine. Note that the one towards the rear of the machine is attached by a screw at the rear of the machine.

9. The Matrix can be emptied – see instructions earlier in the thread, however it isn’t mandatory.

10. Lift the Matrix up and off the push-fit connectors at the bottom of the Matrix. Note the 3 pipes (bottom left of picture) do not need to be disconected from the matrix, however it does mean the Matrix needs to be carefully balanced whilst te rest of the work is done.

11. The Sensor is now accessible. The pipe at the front of the machine should be disconnected, and the sensor assembly can be pulled out of the push-fit connectors.

Once the sensor was disassembled (see earlier in the thread) and thoroughly de-gunked, and the machine reassembled, the machine worked perfectly again.

Many thanks for all contributors to this thread.

Cheers,
Lee.

Hi Jason,

thanks for taking the thread further. Cleaning the original pipe didn’t solve the original problem of the cycle not finishing, so I’m thinking about a fuller uninstall and clean process, and your photos will certainly help.

However, I’d be interested in wether you actually solve the cycle time problem by cleaning the final trap, as it would be a shame to get that far and find it doesn’t fix the problem.

I’m reluctant to do the uninstall as all the pipework is only just long enough to connect to the dishwasher, so will need disconnecting when it is pulled out. Of course the pipes are all behind the backs of the fitted kitchen units, as it was put in by the fitters at the same time that the kitchen was fitted, with no thought to make it easy to disconnect / reconnect the dishwasher.

Thanks,
Lee.

Hi,

I had a go at cleaning the pipe – I thought I’d add some step-by-step pictures covering removing the door and the lower fascia incase anyone else wants to try it. I don’t know wether it has worked yet, but the pipe was certainly gunky.

Before I did this, I drained the sump inside the dishwasher using some tubing, so that I didn’t get water everywhere when I disconnected the pipe.

If this fails to improve things, I’ll have to think about cleaning the other bits, but that will mean uninstalling the dishwasher, and I’m not looking forwards to that.

Thanks for the help.

Hi, Penguin45,

thanks for the lighning response.

As I mentioned, the dishwasher is fully integrated, so when you say

“Power off, lid, door outer, lower cover plate and l/h side off”

does this mean the dishwasher has to be fully uninstalled to get access to the top and left hand side?

From the pictures it seems to be the case, but I thought I’d ask.

Thanks
