Step-by-Step DIY Fix Guide
- SAFETY: No safety risk — open the drawer.
- Identify the item that is too tall — look for anything touching or pushing against the drawer lid.
- Remove the item or reposition it to sit within the drawer height.
- Close the drawer and listen for the lid to click down into place.
- Run a short cycle to confirm the fault is cleared.
If the airflow problem comes back
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- U2 appears with a correctly loaded drawer where all items are clearly within the height limit
What This Error Means
The U2 fault code on your Fisher & Paykel DishDrawer means: An item in the DishDrawer extends above the maximum height limit, preventing the lid from closing and sealing correctly. This is a loading error, not a fault with the dishwasher.
The most common cause is: tall item (wine glass, large pot, tall bottle) extending past the height limit.
This fault is user-addressable. No professional service required for U2 — this is a user loading issue.
Most Likely Cause by Symptom
The Fisher & Paykel dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Tall item (wine glass, large pot, tall bottle) extending past the height limit
Check first: SAFETY: No safety risk — open the drawer.
Common Causes
- Tall item (wine glass, large pot, tall bottle) extending past the height limit
- Item not positioned correctly — leaning against the side rather than upright in the rack
What Not to Do
- Do not force the drawer closed if an item is too tall — this damages the lid mechanism
