Fisher & Paykel DD603I dishwasher Parts

Common problems on the Fisher & Paykel DD603I DishDrawer dishwasher include poor cleaning from clogged filters or a blocked spray arm, draining issues from a kinked or restricted drain hose, and leaks caused by worn seals or O-rings. Many issues improve with cleaning, correct loading, and checking hoses.

Most common symptoms and what they usually mean

• Not draining or water left in the drawer: drain hose kink, blockage, or pump/rotor issue
• Poor wash performance: clogged filter area, blocked spray arm jets, or overloading
• Leaks: worn door seal, heater plate seal, or O-rings; loose hose connections
• No power or intermittent operation: outlet/circuit issue, damaged power cord, or control/display problem
• Won’t start or stops mid-cycle: door not closing/latching correctly, or a fault condition that needs a reset

Quick checks we recommend first (safe, high-impact)

1. Turn off power at the breaker before touching wiring or internal components.
2. Confirm the unit is securely anchored and installed for proper venting and operation (installation issues can cause performance problems). See the installation guide.
3. Inspect the drain path: look for kinks, crushing, or restrictions in the hose run.
4. Check for leaks at connections: inlet hose washer seated, couplings snug, and no drips during a rinse test.
5. Clean and inspect the spray arm: remove debris from the jets and confirm it spins freely.

Parts that commonly solve these problems on DD603I

If cleaning and hose checks do not fix the issue, these DD603I parts are common next steps:

Problem you see	Common part to inspect/replace	What it affects
Water not draining	Drain hose 527137	Drain flow, siphoning, and leak prevention
Leaking from base or around heater area	Heater plate seal 525058	Seals the heater plate area to prevent seepage
Small recurring leaks after service	O-ring, 4-pack 525940P	Seals internal joints and connections
Poor cleaning, debris left behind	Spray arm 527475	Water distribution and spray pressure

Why it matters

Drain and leak problems can lead to repeat fault conditions and water damage, while poor spray performance leaves detergent and soil behind. A short rinse test after any adjustment confirms the drawer fills, washes, and drains correctly.

Ordering the right replacement part

We recommend matching parts by the full model number DD603I and comparing the part name and ID in the parts list. You can order DD603I replacement parts from the parts list for this model, or search by model number on Sears PartsDirect.

To get your Fisher & Paykel DD603I DishDrawer to drain, we straighten any kinks in the drain hose, clear the drain path at the filter plate area, and confirm the drain connection is not blocked. Most draining problems come from a kinked hose, a blocked waste connection, or siphoning.

Quick checks that fix most “won’t drain” issues

• Cancel the cycle and let the unit attempt to pump out (use the cancel/drain steps shown in your installation guide).
• Pull the drawer out slightly and inspect the drain hose for sharp bends or pinches.
• Make sure the drain hose is fully extended and not sagging behind the cabinet.
• Check the sink drain or waste tee connection for a blockage (including any knockout plug that was never removed).
• If you use a standpipe, keep the hose from going too far down the standpipe (too deep can cause siphoning).

Drain hose setup details (installation items that matter)

The DD603I is sensitive to drain hose routing. The installation instructions call out using a drain hose support to prevent kinking and siphoning, and they note the standpipe insertion limit (about 4 3/4 inches) to help prevent siphoning.

What to check	What “good” looks like	What happens if it’s wrong
Hose routing	Smooth curve, no pinches	Slow drain or no drain
Standpipe depth	Not inserted too deep	Siphoning, poor draining
Waste tee connection	Knockout removed, clear path	Water backs up, won’t drain
Drain height	Within the specified max drain height	Weak drain performance

When a part is likely needed

If the hose keeps re-kinking, is split, or is soft/collapsed, replacement is the reliable fix. For this model, we use the correct replacement drain hose 527137.

Why it matters

A DishDrawer that cannot drain will leave water above the filter plate, can trigger fault behavior, and will not wash or rinse correctly. Correct hose routing and a clear waste connection restore normal pump-out performance.

Yes. On the Fisher & Paykel DD603I DishDrawer dishwasher, both drawers operate independently, so you can run both drawers at the same time on separate cycles, or run one drawer while you load the other. For cycle and control details, follow the owner's manual.

How running both drawers works

Each drawer is essentially its own wash compartment with its own controls. That means you can:

• Run two different cycles at the same time (one per drawer)
• Wash a smaller load in one drawer without waiting for the other
• Load one drawer while the other is washing
• Repeat a quick test cycle during setup or troubleshooting (one drawer at a time)

What to check before you run both drawers together

Running both drawers simultaneously is normal, but good setup and connections matter for reliable draining and operation.

• Confirm the unit is securely anchored before operation
• Make sure the drain hose routing is not kinked or twisted
• Verify the drain connection is correct and the unit drains fully after a cycle
• Check for leaks at the water supply and drain connections
• Ensure power is on and the drawer lights up when opened

Quick comparison: one drawer vs. both drawers

How you run it	Best for	What to expect
One drawer only	Small loads, saving water/energy	The other drawer stays available for loading
Both drawers at once	Two loads, different wash needs	Independent cycles; both should wash and drain normally

Why it matters

Using both drawers at the same time helps you keep up with dishes without waiting for a full-size load. It also lets you separate items (for example, glasses in one drawer and pots in the other) while still finishing everything in one window of time.

If you are installing, re-installing, or troubleshooting drain issues, follow the hose and final-check steps in the installation guide.
