Neff S4453N0GB/13 instantaneous heater question.

[Twoten]

Problem with the above machine not cleaning properly.

The only thing I found was the feed did not fluctuate between the spray arms as normal with the Neff dishwashers.

I came to order this from connect and when looking at the image I couldn’t see the motor for the divertor valve on the instantaneous heater pt No 266196 so thought I would check if this heater box normally has the divertor.

I thought all the Neff dishwashers use this system but thought I’d better check before ordering.

Can anyone advise?

Thanks.

Not all models have the water point system. This model doesn’t have it as it’s one of the early machines using the base IWH so you get feed to both spray arms at the same time.
Some models do have a ‘top basket only’ wash cycle though but it uses a different sytem which i’ve never actually seen.

That explains why the water didn’t alternate between the upper and lower spray arms then!

This still leaves me with a problem, the dishes are not cleaning properly, according to the customer the dishes are left with small particles of food on.

The spray arms are clean, nothing preventing them turning. The machine heats, water level seems OK, no blockages in the float chamber or sump hose. No debris under the lower door seal. Water softener in the house so salt not used. Rinse aid ‘apparently’ topped up weekly. Using a quality detergent and rinse aid.

Have I missed anything?

Is top basket engaging correctly with water entry fitting at rear?

Re: Neff S4453N0GB/13 instantaneous heater question.

The machine sounds as if it is pumping enough volume of water round and not making any strange noises.

Not sure about the top basket engaging at the rear, will this appear obvious if not correct?

I did check to make sure the tube was fitted correctly into the back of the filter though.
