My Fisher and Paykel Aquasmart leaves more dirt and lint on clothes than when they went in. The company is no help at all

Your Aquasmart machine requires 4 new suspension damper rods & 4 top bands, these are a common problem for AquaSmart machines.

WASH PERFORMANCE INFORMATION
12.1 Creasing
Creasing can be caused by over loading SmartDrive or the dryer. Permanent Press or Delicate
cycles have been designed to minimise creasing as they use a lower spin speed. Do not leave wet
clothes to sit in the washer or laundry basket.
12.2 Soiling
Soiling is the result of insufficient detergent for the load. White clothes are better washed
separately. Separate lightly and heavily soiled items, as clothes can pick up soil from dirty wash
water. Cold water below 20oC does not wash effectively. Select the wash temperature according
to soil type. For example, blood and mud are better washed in cold water, while sweat and oil
based soil wash better in warmer water. Loads made up of articles of varying sizes will wash
better (e.g. full loads of sheets may not wash that well). Hard water requires more detergent than
soft water.
12.3 Linting
Wash lint givers (eg. towels, flannelette sheets) separately from lint collectors (eg. synthetic
fabrics). Over loading SmartDrive can increase the likelihood of linting. Insufficient detergent for
the load can increase linting as there will not be enough detergent to hold the lint in suspension.
Over drying synthetic fabrics in a dryer can cause a build-up of static electricity and result in the
fabrics attracting lint.
12.4 Detergent Residue
Over loading SmartDrive can result in detergent residue being caught in the creases of the
fabrics. If this occurs, decrease the load size. Some detergents need to be pre-dissolved. Check
the instructions for the detergent. Cold ambient temperatures, cold washes or short agitation times
may not let the detergent dissolve properly. In these cases pre-dissolve the detergent.
Overdosing of detergent can also cause residue when foam breaks down and will show as white
specs on the clothing. Poor quality detergents can result in residue.
12.5 Black Marks on Clothes
A build up caused by the interaction of fabric softener and detergent (scrud) can flake off and mark
clothes. Do not use too much fabric softener, maximum 75cc. If this is a problem, it is
recommended that SmartDrive is periodically filled with hot water, plus 1-2 cups of dishwasher
powder and left to soak.
12.6 Grey Marks on Clothes
Not enough detergent for the amount of soil on the clothes can result in grey marks on clothes. If
this is a problem it is recommended that SmartDrive is periodically filled with hot water, plus
detergent and left to soak.
12.7 Dye Transfer
Wash and dry non-colourfast clothes separately. Non colourfast clothes left sitting in a washer or
laundry basket can transfer dye to other clothes.
12.8 Tangling
Washing with too much water (i.e. under loading) can cause the clothes to tangle around each
other. Do not load SmartDrive by wrapping clothes around the agitator.

Fault code 49 is water valves, But the Aqua-Smart board is outputting the wrong code here, The Smart pump has blown the water valves fuse, A common thing in Aqua-Smart Machines.
The Smart pump has jammed with lint and caused over current to the board and taken out parts on the board that drive the pump.
Best to get a new/recondition board for your machine.

The damper suspension rods and bands are worn and need replacing.

shouls not make any diffrence but i dont know you original question ?

Bearing seals shot

i would say its one of the boards usually the main motorcontroller

Water inlet solenoids is the usual problem.

Hi just read your posting.Now from the information in your posting it tells me you have tried all the settings and cycles and still the soap is present on the clothes at the end of the cycle,Is this correct?Have you tried a cycle with the EFFICIENCY button switched off and in the Regular setting?Have you tried a liquid detergent?Please reply with additional information on the questions and I am sure I can help you rectify this fault.Looking forward to your reply.
