BOSCH MAXX Dishwasher SGS45E08GB/45 Bottom Tray Not Cleaning

[garyf]

Hi, I have a BOSCH MAXX Dishwasher SGS45E08GB/45 TYPE S9G1B.
The dishes in the bottom tray are not getting completely clean. I have checked the drain outlet as per advice on previous threads, I did get some crud out from under the small panel in the bottom of the filter housing, and also disconnected the drain hose at the bottom of the plastic manifold on the machine right hand side and sucked water through from the filter housing using a pump, so I am pretty sure that the drain route is clear.
Top and bottom spray heads are clear, and I ran the machine empty with both heads off, on a full cycle with a cleaning agent. Whilst this was happening I had both side panels and top panel removed. I could feel the water jet hitting the top of the machine, so assumed this was coming from the bottom spray supply? I looked at the side spray on the left hand side of the machine, but couldn’t see any water going through the plastic hose to the spray head.
Is there some sort of diverter valve that should send water that way?

Thanks in advance

This machine has an alternating valve as part of the heater assembly; it may well have failed. P/no is 493333 – £63 plus the usual. spares@ukwhitegoods.co.uk will get you one promptly.

However……….. Fitting is a demolition job involving removing the cavity from the base – you may like to consider professional help. Click the link below.

Power off, if you are going to do this yourself.
