Bish-Bosch dodgy wash! SGS 43A12 GB/27 Exxcel problem

[brightspark]

Hi there,

I’ve got a nice new s/h Bosch Exxcel SGS 43A12 which I had thought a real bargain at 50 quid 😉 . It washed very nicely thank you the first time I used it, but now doesn’t clean so well, and the dispenser always has some (and sometimes alot) of dishwasher powder left in it in a soggy lump. The dispenser always opens fully, right near the start of the wash (when I’ve interupted the wash to check).
I’ve checked and cleaned the filter/mesh inside the machine, and also checked out the spray bars and they all look clear. What else should I be looking for?
The salt and rinse aid are topped up, and the machine seems to fill and empty OK, though as I’ve only had it a few days I can’t say if the occasional groaning/squeeking noises it makes as it goes through the cycle are normal or not. It makes alot less noise than my old Zannussi DW401 though.
On the main wash cycle (55-65 Auto) it has had 144 minutes on the indicator, and has taken that long.
The eco cycle is shorter, but also has the same problems.
I don’t have a user guide, but it seems straightforward enough to use (if working ok!).

Yours hopefully,

Adrian

Adrian,

Do ensure you top up the salt container when the salt light comes on, check and clean both spray arms very carefully under the tap.

Might be a good idea to stop the machine after its been running for say 5 minutes to check as to how much water is in the tub, it should be lapping the salt container cap!

Sounds like spray arm problem to me.

Remove arms and run under tap,make sure water runs freely from all holes on arm.Knock arm against your hand to remove any bits and keep rinsing out.

Also make sure nothing is obstructing the top arm,usually a d/w freshener or long knife in cutlery basket.Put top basket on highest setting to try and avoid this.

Thanks Martin – I’ll check the water level tonight.

Thanks Boro, I only did a visual check on the spray arms, so I will try flushing them through under the tap. I’m pretty religous about checking for spray obstructions in the machine (I always give them a quick spin before starting it off) so thats probably not the problem, but I will try putting the top basket on the higher setting.

Hi
On Auto it utilises the turbidity sensing part of the appliance, in as much it looks at water quality and adjusts the duration of the wash accordingly.
I have had a faulty module not instigating teh diverter unit on the heater unit thus not supplying water correctly to either top or bottom depending on where it was when module failed.
Hope that helps.

Thanks Greg,

Thats interesting, but a bit worrying in that the machine must have some sensors, presumably optical, to work out murky the water is. If so there must be some chance that those sensors get covered in crud over time and so become less accurate. I guess it must do the pre-rinse cycle and then suss out how dirty the rinse water is after that?
When I was checking the filters/screens, the “sump” water inside the machine was very murky indeed. I baled most of that out to see if anything was wedged “down below”, and that seems to knock 20 mins off the “auto” cycle.

Thank you for your confession, clearly your sins will now be washed away as a result of learning that dishwashers clean dishes but have no ability to clean themselves, Amen!

Yes, and verily I have seen light Master, and doubly guilty am I, as clean the washing machine out regularly I do 😳 .
But “Dishwasher, cleanse thyself” does have a persistant, if illogical attraction. Are these dishwasher cleaners really effective, or is it a question of “chuck it in and pray”? Are there any that you’d recommend?
I’ve checked the water level during the cycle and it was just below the salt lid as recommended, flushed the spray arms through with hot water, and they seemed clear, but there still seems to be some powder residue in the dispenser. The main screen at the bottom of the machine is clear, and the two filters (the one that rests under the screen and the more complex one that “plugs in” to the screen on top of the other filter. Is there anywhere else I should be looking for other filters/potential water flow blockages?

No Brightspark, seems now you have all points covered and your 50 quid machine should work wonders from now on in 😀

Finish Dishwasher Cleaner and others?………..nah!….leave them on the supermarket shelf I would. Just top up the salt and rinse aid every month or so, clean the filters regularly and you’ve got it sussed!

Powder residue?…also not a problem and most likely caused through trying to wash a full load on a ‘quick wash’ or ‘economy wash’ cycle.
