Important Tips for Fisher & Paykel Models

  • Some DishDrawer models include a Keylock/child lock and ‘knock-to-pause’ feature that can prevent drawer from opening until disengaged

Possible Causes

Faulty or seized door latch/locking mechanism

How to Identify: Dishwasher completes cycle but door remains latched, requires excessive force to open; related errors like ‘Door Lock Error’ reported in manuals for lock issues

Part: Door latch / lock assembly

Child lock / Keylock or knock-to-pause feature engaged (DishDrawer models)

How to Identify: DishDrawer won’t open despite cycle finished, lock indicator shown or keylock activated; Fisher & Paykel support lists keylock related to inability to open drawer without disengaging lock first

Part: Control panel lock feature

Misalignment of door or drawer tracks/latches

How to Identify: Door feels crooked, doesn’t seat flush, or misaligned relative to frame, making opening/closing difficult

Part: Door hinges/tracks and strike plate

Obstruction by racks or interior items

How to Identify: Racks or dishes protruding when closing can jam mechanism and prevent opening

Part: Dishwasher interior/drawer tracks
