Bosch SMS 69T18AU check water supply error

[orinoco]

Brand new dishwasher won’t work and keeps giving “check water supply error” after a few minutes of starting.

I have exhausted all avenues I can think of:
Bosch service can’t help;
Water supply authority can’t help;
Plumber can’t do any more (already spent $500 on plumber);
Service technician can’t help;
Local retailer can’t help me find a model that will work.

I have a low flow apparently… of only 7.5 litres per minute at the water inlet connection point.

Is there any way around this on the Bosch?

Is there a make and model that isn’t so sensitive to low water flow?

Can’t believe I am (it seems) the only person in Melbourne Australia with this issue…

its a problem with a lot of modern appliances where the water pressure is low

in the area where you live do other people have low water pressure problems ?

you could add a pump to raise the pressure.

Hi Dave,

Yes the neighbours also have low pressure.

I am coming around to the idea of the pump to increase the pressure… I would prefer to buy another dishwasher if I knew it would work rather than introduce a pump (and hence another potential point of failure).

If I do go down the pump road then I have to weigh the pros and cons, I don’t have a lot of room for a pump.

Thank you for the reply,

Justin

have you asked you neighbours what units they have ?

might give you a clue as to which ones may work

Yep – they have a bosch! But not as old as mine.

Will ask the other neighbours on the weekend…

Spoke before to an experienced technician and he has come across the problem a few times… he recommends a booster pump to fix the problem as well.

I will have to get serious about researching a pump.
