Fisher & Paykel “DishDrawer”

[subs]

Intergrated DD603i i think!
A friend of mine asked me to have a look at this dishwasher for him. I have never worked on one of these before but would like to help him out.
The problem was the bottom drawer was “not draining away the water”.
When i had a look i managed to remove the drawer and could see that it is quite different to “normal” D/W’s. Each drawer seems to operate independently from the other. I could see they each have a water inlet and outlet which seems to be fed straight to the small wash motor in each drawer. Part of the motor lifts out once you have removed the spray arm, and i noticed it has two impellors (does it double up as an outlet pump).I did notice that the spray arm did not seem to clip on to anything it just seemed to sit on top of the motor but my friend does not remember it being like that before. How and where does it heat the water. Where do i start with this no drain fault on this appliance. Im quite good around your average D/W but this is totaly unfamiliar to me.
Sorry about the long ramble!
Any help please!

The spray arm, motor etc is supposed to lift out! Yes it is unlike any other dishwasher.
Once the rotor etc is out you will see a passage that the drain water needs to pass through to get to the outlet hose. (you can see the hoses and general layout by looking up at the underside of the top draw when it is pulled out.) Chances are that the passage is blocked, easy to clear.

Thanks for reply Eastlmark.

Just to familiarise myself with the basic workings of this machine before i go back and have another look.

Does the wash motor pump out the water too, if not where is the outlet pump?

Where is the water heater, is it behind the door facia and is there one for each drawer?

Thanks

The wash motor goes in reverse and speeds up to empty. The heater is the blue coloured metal plate that you see between the wash motor and the bottom of the basket.

Re: Fisher & Paykel “DishDrawer”

Both draws are completely independant of each other save for a mutual power pcb which is in the base of the housing. Each have their own circ pump and heater. The impellor at the top of the rotor is the circ pump while the one at the bottom is the drain pump, it rotates in reverse to drain. the heater is part of the plate around and beneath the pump motor. wierd as hell but not to bad to work on, make sure they pay you well though!

The motor is a fully electronically controlled 80V, 60W, 3 phase. 6 pole brushless DC motor, running on wash at 2300 – 2850rpm depending on the cycle selected and at approximately 4200 rpm on Drain. The rotor is a four pole permanent magnet rotor with a graphite bearing at each end of the vertical shaft, At the lower end of the rotor is the drain impelllor and at the other end is the wash impellor.

The Element is clamped in place by a lockring nut and supports the motor at the base of the tub. The lockring nut holds the heater plate into the base of the tub and the motor housing assembly to form a watertight seal.
