Bosch lower spray arm not rotating

[DaveGibelli]

Hi

I have a SRS56A02GB/13 that is working ok but the lower arm is not rotating. It is clean and undamaged, it rotates freely by hand but is always in the same position and the bottom plates are not as clean as they should be.

The top is fine. To get at the internals requires a complete strip down, I would like to get the right part before stripping it…

Any ideas?

Dave

Heater assembly has an alternator valve in it – this switches the water between the top and bottom rotors. It will have mechanically jammed or electrically failed.

Thanks for your wisdom…I hope you are right!

Just ordered the part via the link below…whopping 80 squids 😥 👿

How easy is it to fit? (dumb question I know ‘cos it depends on ability) :rolls:

Er, you won’t like it much…… The entire stainless cavity has to be removed amd the door dropped off its hinges. It is basically a screwdriver job, but very time consuming if you’re doing it for the first time.

Two of the biggest understatements of 2008!

For anyone else attempting this I agree 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} with the above quotes…

However, Penguin45 was correct in his diagnosis. There is a motor attached to the heater that directs the water flow. This is a weak point in the design because water can leak past an internal seal leading to corrosion around some internal contacts that control the motor. Therefore, nobody can repair the components…replacing the expensive heater assembly or buy a new dishwasher are the only options.

Penguin, thank you again for your expertise!

Well the SAME fault is back less than 3 months after changing the heater/diverter assembly!

Looks like the replacement part has died… 😈

Are the replacement parts patten or genuine?

There won’t be a pattern version!

Have you check to see if it is blocked up. All the ones I’ve had have been blocked, so luckily I haven’t had to change one of these yet :snig:

The old one was badly corroded as you might expect after about 6 years of daily use…I fitted a new filter when I changed the assembly and it has been working a treat until now.

I will order a new part as I don’t want to strip it down without having the spares to hand.

I will let you know what I find…
