Re: bosch dw
The turbidity sensor located in the heater unit dictates the time wash cycles take for the most part. The time is held in memory and based on the previous wash cycle will be applied to some degree to the next. Now if the sensor is crudded up with years of silt and staining (bit liked a misted up windscreen) it miss-reads the state of the water passing through it and maintains longer cycles times as a result. In cases like that only replacing the sensor will remedy the fault.
Slow fill, drain and heat times also affect its memory retention.
Having said all that, I’m assuming the machine completes the wash cycles successfully otherwise does it?
Re: bosch dw
Use of ‘all in one’ detergents can also cause this fault due to overfoaming with the bosch low water level. Get customer to run a couple of cycles empty with no detergent and see if times drop.If they do then get them to use separate salt/rinse aid and detergent only. If they don’t then the water level is probably too low( crud in side chamber/faulty flow sensor if fitted). Wizard
