What Not Cleaning / Film means (fisher paykel dishwasher not cleaning)
When a fisher paykel dishwasher not cleaning or leaving film is the concern, it is an observable condition. A blocked or loose spray arm (which can show U6 or A6), a dirty filter, wrong detergent, or hard-water film are the usual causes, most of which are owner-fixable.
Symptoms to look for (fisher paykel dishwasher not cleaning)
Poor cleaning is something you read off the dishes themselves once a cycle ends. Food residue left on plates, a chalky film on glassware, or cups that come out cloudy and spotted all point to water not reaching the load with enough force or chemistry. The decline is usually gradual as a filter loads up or limescale builds, though a U6 or A6 code can flag a spray-arm problem more directly. Check what you are actually seeing against the list below before deciding it is a hardware fault.
- Dishes come out with food residue or film
- Glasses look cloudy or spotted
- Cleaning has worsened over time
- U6 or A6 may appear
Likely causes
Good cleaning depends on three things working together: water delivered with force, clean recirculated water, and the right detergent. Most film-and-residue complaints trace back to one of those slipping — a spray arm that is blocked or sitting loose, a clogged filter, or hard-water deposits. Happily, most are owner-fixable, so the aim is to clear the simple causes before any trained service or Fisher & Paykel parts come into it.
- Blocked or loose spray arm — water is not delivered well
- Dirty filter — recirculated water is soiled
- Wrong or low detergent — poor cleaning
- Hard-water film — needs rinse aid or a cleaner
What you can check
This is one of the more rewarding faults to tackle yourself, because cleaning and chemistry fixes solve most cases. Pull and rinse the filter, clear the spray-arm jets and click the arm back firmly, confirm you are using dishwasher detergent in the right dose, and run a dishwasher cleaner if film has built up. Note any improvement at each step; if cleaning stays poor afterwards, that record helps a technician focus on the wash pump. Leave live wiring and sealed parts to a qualified technician.
- Clean the filter and the spray-arm jets, and refit the arm firmly.
- Use the correct dishwasher detergent and rinse aid.
- Run a dishwasher cleaner if film has built up.
- If cleaning stays poor, book service to check the wash system.
Parts a technician may check or replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the spray arm, filter, detergent/rinse aid, and water temperature. The correct part for your Fisher & Paykel Dishwasher is matched from the model and serial number, and genuine components are fitted through trusted parts suppliers rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
Poor cleaning with a clean arm, filter, and correct detergent needs a technician to test the wash pump. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.
Prevention and care
Clean results stay consistent when the wash system stays clean. Rinse the filter on a regular schedule, keep the spray-arm jets clear of debris and seated firmly, and run a dishwasher cleaner periodically if you live with hard water. Topping up rinse aid keeps glassware from spotting, and matching detergent dose to load and water hardness does the rest. If cleaning still slips after all that, note when it began so a technician can move quickly to checking the wash pump rather than the basics.
