My machine is now 5 yrs old and has functioned perfectly all it's life. Over the last 3-4 months, it has been refusing to fully pump-out, leaving around 1.5 to 2 litres of water in the bowl, which submerges the element and the load therefore remains wet. we had a serviceman call. he pumped it out using the diagnostic functions check; he then checked the hoses for blocking or kinking, but no problem exists. he then suggested the drain hose was too high; (it had worked perfectly beforehand;) but we lowered it by about 30mm as he required. The lower drawer does not have a similar problem. I have thoroughly cleaned the filters; even swapped the impellors from one bowl to another, but not had any success. I phoned F & P in NZ to try and access the diagnostic procedures, but they would not help; suggested we call in serviceman again; very expensive! Is there a timer which controls how long the pump operates? or, is the pump-out function governed by a sensor? We do not get any error codes, just this annoying excess of water remaining in the bowl. The owners handbook states that any excess water must be soaked up manually; I have done this on several occasions, but the problem will not go away. Please advise what else I can do?
WOW! I have the same problem with my top Drawer. I have been draining the water manually by suction, now all I do is hit the power button and then hit the start button. The drain function starts and completely drains the Drawer. Thanks for the tip!
I have the same problem with my top Drawer. To drain the water manually without having to suction it out, this is what I do. I hit the power button and then hit the start button. The drain function starts and completely drains the Drawer. I hit the power button again to shut it down before the fill cycle starts. I think the problem is the timer shutting down the pump too early. I don't want to spend the $$ on a service call until I know they will fix the problem the 1st time.
Please clarify "The lower drawer does not have a similar problem." did the "but we lowered it by about 30mm as he required." make any difference? run this test: disconnect power to the unit. then find and disconnect the drain pump's wires (or connector). then apply power to the pump (I am assuming you have a 115VAC house supply) by a separate wire cord. run the pump on this cord until you see all the water pump out. if it does, then your timer is shutting down the pump too early. the water level sensor is mostly used for the other case during water fill only.

Sorry I was a bit late compiling my answer. These dishwashers comprise 2 drawers, upper and lower; the upper unit is the largest of the pair. The pumps used in each are identical, so I have swapped the rotors over to see if one is more efficient than the other, but no improvement shows. Each pump has an external stator; it is of a 6-pole motor and is an integral part of the bowl. It is controlled by an on-board computer, which makes it difficult to 'liven-up' and test as a unit. The pump does function OK but appears not to run long enough while the final drain-out cycle takes place. My query is to either find an adjustment time for the pumpout cycle, or to manually pump out the bowl so the drying element is allowed to get hot enough to dry the load. Footnote; When we lowered the drainhose loop by 30mm, there was a slight noticeable improvement, but the original installation was as per F&P instructions. If it had have been incorrect, why did it fonction OK for the first 4 years?
