How do I get my Fisher and Paykel DishDrawer to drain?
To get your Fisher & Paykel DD603I-88271 DishDrawer to drain, we start by clearing the drain filter and filter plate, then make sure the drain hose is not kinked or pushed too far into a standpipe (which can cause siphoning and poor draining). Use the steps in the owner's manual to access and clean the drain area safely.
- Cancel the cycle and restart a Rinse program to force a drain at the end of the cycle.
- Remove and clean the drain filter and filter plate (food debris here is the most common cause).
- Inspect the drain hose path for kinks, pinches, or crushing behind the cabinet.
- If you use a standpipe, keep the hose from extending more than about 4 3/4 in. (120 mm) down the standpipe to help prevent siphoning.
- Confirm the installation drain setup stays within the maximum drain height of 37 1/2 in. (950 mm).
The DD603I-88271 is sensitive to hose routing. A hose that is kinked or routed without support can restrict flow and leave water in the tub.
| What to check | What “good” looks like | What happens if it is wrong |
|---|---|---|
| Hose routing | Smooth curve, no sharp bends | Slow drain, standing water |
| Standpipe depth | Hose only goes a short distance into standpipe | Siphoning, poor drain |
| Drain height | At or below 37 1/2 in. (950 mm) | Drain errors, incomplete draining |
| Hose condition | No soft spots, splits, or deformation | Leaks, weak drain flow |
If the hose is damaged or keeps re-kinking, replacement is the reliable fix; use the model-matched drain hose 527137.
A restricted drain can cause dirty water to recirculate, leave odors, and trigger fault beeps or incomplete cycles. Keeping the filter plate, drain filter, and drain hose clear protects the pump and improves wash performance.

What does U6 mean on a Fisher & Paykel dishwasher?
On the Fisher & Paykel DD603I-88271 DishDrawer dishwasher, a U6 fault points to a spray arm problem, most often a spray arm that has come loose or come off its mount. It can also show up when wash water pressure is too low to spin the arm properly; check the spray arm and filters first using the owner's manual.
- Pause the cycle and open the drawer; confirm the spray arm is seated and spins freely by hand.
- Remove any tall items (cutting boards, sheet pans, utensils) that can block the spray arm.
- Clean the drain filter and filter plate area; restricted flow can reduce spray pressure.
- Verify the spray arm holes are not clogged with food debris.
- Run a quick rinse cycle after re-seating the arm to confirm the code clears.
If the spray arm is cracked, warped, or won’t stay secured, replacement is the most reliable fix.
| Symptom you see | Most likely cause | What we recommend |
|---|---|---|
| Spray arm falls off or wobbles | Worn hub or damaged arm | Replace the dishwasher spray arm 527475 |
| Dishes dirty on one side | Arm blocked or holes clogged | Clean arm holes; reload dishes to prevent contact |
| U6 returns after cleaning | Low circulation from restriction | Clean filters; check for obstructions in the sump area |
The spray arm is what distributes wash water across the dish load. If it is loose or not spinning, the dishwasher can’t maintain proper wash action, so you will see poor cleaning, leftover detergent, and repeated fault codes.
- Load heavier items toward the outside so the arm has clearance.
- Keep utensils from dropping through the rack and contacting the arm.
- Clean the filter area regularly, especially after heavy soil loads.

What are the commonly replaced parts in a dishwasher?
In a Fisher & Paykel DD603I-88271 dishwasher, the most commonly replaced parts are the ones that handle washing action, sealing, draining, and dispensing detergent. When cleaning performance drops, leaks start, or the unit will not drain, these parts are the first places we check; see the owner's manual for model-specific care and cleaning steps.
- Spray system: spray arm and related seals; poor cleaning, no spray, or arm not rotating
- Sealing parts: door seal and O-rings; leaks around the drawer or moisture at the front
- Drain components: drain hose and drain filter area; standing water or slow draining
- Detergent dispensing: detergent dispenser; detergent not releasing or poor wash results
- Heating and sealing surfaces: heater plate seal; leaks or heating-related performance issues
- Controls and user interface: buttons, display window, display boards; dead panel, stuck keys, or unreadable display
These are examples of commonly replaced items available for DD603I-88271:
| Symptom you notice | Likely area | Example part on this page |
|---|---|---|
| Dishes not getting clean, arm not spinning | Wash action | Dishwasher spray arm 527475 |
| Water leaking at the drawer/door | Sealing | Dr seal kt 527504 and dishwasher o-ring, 4-pack 525940P |
| Not draining or drain connection issues | Drain path | Dishwasher drain hose 527137 |
| Detergent not dispensing correctly | Dispenser | Dishwasher detergent dispenser 524887 |
These components see the most wear because they are exposed to heat, detergent, food soil, and movement every cycle.
- Hard water and detergent buildup can restrict spray and clog filters
- Food scraps can collect in the drain filter area
- Seals compress and age, then start to seep
- Buttons and display parts wear from repeated pressing and moisture
We recommend these simple checks first because they often restore performance without replacing anything.
- Make sure nothing is blocking the spray arm (cutlery or large bowls can stop rotation)
- Clean the drain filter and check for food particles
- Use the detergent type recommended for this DishDrawer style (the manual calls for powdered detergent)
- If you use a cleaner/descaler, run a detergent wash immediately afterward
