Fisher & Paykel DS603I dishwasher dish drawer Parts

To get your Fisher DishDrawer model DS603I to drain, we focus on the most common causes first: a kinked or sagging drain hose, a blocked drain connection, or a clogged filter area. Correcting hose routing and clearing the drain path typically restores normal draining.

Quick checks that fix most draining problems

• Turn off power to the DishDrawer at the breaker before handling wiring or removing components.
• Pull the unit forward enough to inspect the drain hose routing; straighten any kinks and remove any pinches.
• Make sure the drain hose is fully extended so it does not sag, and that the drain hose support is installed to prevent kinking and siphoning.
• Confirm the drain connection is open (any knock-out or plug at the waste tee or disposal inlet must be removed).
• If you are using a standpipe, keep the hose from going too far down the standpipe (too deep can cause siphoning and poor draining).

Drain hose setup guidelines (DS603I)

Use these installation limits to prevent slow drain, siphoning, and standing water:

Item	What to do	Why it matters
Maximum drain height	Keep the drain height at or below 37 1/2 in. (950 mm)	Higher routing can prevent the pump from pushing water out
Standpipe insertion	Do not extend the hose more than 4 3/4 in. (120 mm) down the standpipe	Helps prevent siphoning and backflow
Hose routing	Keep hose fully extended, supported, and unkinked	Prevents restrictions that stop draining

When a part is likely needed

If the hose repeatedly kinks, is split, or feels soft and collapsed, replacement is the reliable fix. For DS603I, the correct replacement is the drain hose 527137.

Why it matters

A DishDrawer that cannot drain can leave excessive water above the filter plate after a rinse or wash, which reduces cleaning performance and can trigger drain-related faults. Proper hose height, support, and an open drain connection keep the pump working efficiently.

For diagrams and the exact drain-hose connection method for DS603I, follow the steps in the DS603I installation guide.

On the Fisher & Paykel DS603I DishDrawer dishwasher, we find the model and serial number on the rating label located just inside the drawer opening, typically along the left-hand side of the tub opening area. Check the label before ordering parts or scheduling service.

Where to look on the DS603I

• Open the DishDrawer fully.
• Look along the inside edge of the tub opening (not the outer cabinet).
• Focus on the left-hand side first.
• Check for a rectangular rating label with printed text.
• Write down both the model number and the serial number.

What the label usually includes

Label item	What it’s used for	Example for this page
Model number	Matching parts and diagrams	DS603I
Serial number	Production details and service identification	Varies by unit
Electrical ratings	Installation and troubleshooting reference	Varies by unit

Why it matters

We use the exact model number to match the correct Fisher & Paykel dishwasher parts, especially for control panel and display components where small design changes can affect fit and wiring.

Helpful next steps

• Confirm the model number reads DS603I exactly.
• Use the model number when checking diagrams in the DS603I owner’s manual.
• If you’re replacing a user interface part, match the part ID carefully (for example, dishwasher control panel button set 526454 or dishwasher display window 526212).

On the Fisher DishDrawer model DS603I, diagnostics are run from the control panel using a built-in service/diagnostic mode that lets you step through component tests and view fault information. We follow the exact key sequence and test meanings shown in the DS603I installation guide and the DS603I manual.

Before you start (important safety)

• Turn off power at the breaker before removing panels or touching wiring.
• Keep hands clear of moving parts when a test runs.
• Make sure the drawer is fully seated and can close normally.
• Confirm the water supply valve is on and the drain hose is not kinked.
• If the unit was just installed, complete the final checks first (rinse test and leak check).

How diagnostics typically work on a DishDrawer

Most Fisher DishDrawer diagnostic modes follow the same flow: enter diagnostic mode, select a test, then watch the display for a code or response.

• Put the drawer in standby (not running a cycle).
• Enter diagnostic mode using the model-specific button sequence.
• Step through tests (examples: heater/element relay, drain pump, fill valve, lid actuators, display/backlight).
• Exit diagnostics and run a quick rinse to confirm normal operation.

What to do if a fault shows up

The installation instructions call out that if a fault occurs, you should consult the fault code section in the user guide and then re-check water supply and drainage connections.

Quick checks that fix many “fault” situations

• Clean the filter area and check for debris around the spray arm.
• Verify the drain path is clear and the drain hose has a proper high loop.
• Confirm the drawer closes fully and the lid seal can engage.
• Power reset: turn the breaker off for 1 minute, then restore power.

Common symptoms and the most likely area to test

Symptom	What to test first in diagnostics	Related part you may need
Won’t drain	Drain pump function, drain path	Drain hose 527137
Poor wash / low spray	Spray arm rotation, blockage	Spray arm 527475
Buttons not responding	Keypad/UI response	User interface control button assembly 526618P

Why it matters

Running diagnostics on the DS603I helps you separate a simple installation or blockage issue (water supply, drain routing, leaks) from a failed component like the spray arm, drain hose, or user interface.

On the Fisher & Paykel DS603I DishDrawer, a flood switch trip usually clears after you stop the cycle, turn power off for a few minutes, then restore power and remove any water that collected in the base. If the fault returns, fix the leak or drainage issue that triggered it.

Quick reset steps (DS603I)

• Press Power once to stop the beeping and pause operation.
• Press Power again to turn the DishDrawer off.
• Wait 3 to 5 minutes.
• Press Power to turn it back on.
• If the unit still indicates a flood condition, remove standing water and correct the cause (leak, oversudsing, or drain restriction).

What to check if the flood fault comes back

A flood switch is doing its job when it keeps returning; it is sensing water where it should not be. Check these common causes:

• Drain path restriction: kinked drain hose, blocked waste tee, or a plug/knockout not removed at the drain connection.
• Drain hose routing: excess hose length pinched or routed incorrectly.
• Water supply leaks: seepage at the inlet hose connection or valve.
• Drawer sealing issues: door seal not seating, debris on the sealing surface.
• Overfilling symptoms: water left above the filter plate after a rinse.

Parts that are often involved

If you find a physical leak or a worn seal, these model-matched parts are commonly replaced:

• Dr seal kt 527504 (drawer/door sealing)
• Drain hose 527137 (kinks, splits, or loose connections)
• O-ring, 4-pack 525940P (sealing points that can seep)

Why it matters

A repeated flood switch trip prevents the DS603I from running to protect your cabinetry and the dishwasher’s electronics. Clearing the water without correcting the leak or drain issue typically makes the fault return.

Helpful reference

Symptom you see	Most likely area	What to do next
Water remains above filter plate after rinse	Drain hose or drain connection	Check for kinks, blockages, and proper drain hookup
Water around supply/drain connections	Hose fittings	Tighten connections and recheck for leaks

On the Fisher & Paykel DS603I DishDrawer dishwasher, fault code A3 means the drawer cannot drain. In most cases, clearing a blockage in the drain path (filters, sump area, drain hose, or sink connection) restores normal draining; then you can clear the fault and resume the cycle using the control panel.

What to do first (quick checks)

• Press Start/Pause once to stop the beeping.
• Press Start/Pause again to clear the fault, then restart the wash.
• Remove and clean the filter area; clear any food debris from the sump.
• Check the sink drain/disposer inlet where the dishwasher drain connects; clear buildup.
• Inspect the drain hose for kinks, crushing, or a sag that traps water.
• If you recently installed the unit, confirm the drain routing meets the installation requirements in the DS603I installation guide.

Drain setup details that commonly trigger A3

A3 often shows up when the drain hose is routed incorrectly or the drain height is too high.

Item to verify	What “good” looks like	What causes A3
Drain height	Drain routing stays within the unit’s allowed maximum	Drain loop/standpipe too high so the pump cannot push water out
Hose routing	Smooth path with no sharp kinks; excess hose managed	Kinked hose, crushed hose, or low spot holding water
Connection point	Clear sink/disposer inlet	Clogged inlet or blocked plumbing

When a part is likely involved

If the hose and plumbing are clear but the drawer still will not drain, a failed drain component is likely.

• If you see leaks or soft spots in the hose, replace the drain hose 527137.
• If you hear the motor running but water does not move, check for an obstruction at the pump inlet.
• If the unit is silent during drain or repeatedly faults, the pump motor circuit may need diagnosis.

Why it matters

A DishDrawer that cannot drain will stop mid-cycle to prevent overflow and poor wash results. Fixing the drain path quickly helps protect the pump motor, improves cleaning, and prevents standing water and odors.

Yes. On the Fisher & Paykel DS603I DishDrawer dishwasher, many common repairs are DIY-friendly if you shut off power at the breaker and turn off the water supply first. Simple mechanical parts (seals, hoses, buttons) are usually straightforward; wiring and control issues take more skill.

What you can usually replace yourself

• Door and drawer sealing parts (leaks around the tub edge)
• Spray components (poor cleaning, no spray)
• Drain hose and clamps (leaks, slow draining)
• Control panel buttons (stuck, broken, missing)
• Small hardware like pins and covers

Repairs that are more advanced

These are still doable, but we recommend using the wiring diagrams and step-by-step procedures in the documentation.

• User interface and display components
• Pump motor or motor/rotor assemblies
• Internal seals around the heater plate area
• Any repair requiring wire testing with a multimeter

Parts that match common DIY symptoms (DS603I)

Symptom	Common DIY check	Example part for this model
Drawer will not drain	Inspect for kinks, leaks, loose routing	Dishwasher drain hose 527137
Poor wash coverage	Check spray arm for clogs, cracks, binding	Dishwasher spray arm 527475
Buttons not responding	Look for broken or missing keys	Dishwasher control panel button set 526454

Safety and prep checklist (do this first)

• Turn off the house fuse or open the circuit breaker.
• Turn off the water supply valve.
• Protect the power cord from damage when moving the unit.
• Keep the DishDrawer upright if relocating it to prevent water spillage.
• Plan for future service access; the unit must be installed so it can be removed later.

Why it matters

DishDrawer units like the DS603I pack plumbing, electrical, and sealing surfaces into a tight space. Doing the shutoff and access steps correctly prevents leaks, shock hazards, and repeat failures after the repair.

For model-specific procedures, clearances, and connection requirements, use the DS603I installation guide and your DS603I owner's manual.

A bottom leak on a Fisher & Paykel DS603I DishDrawer usually comes from a sealing problem at the drawer (door seal area) or a leak at the water supply or drain connections. We focus first on confirming the leak source, then correcting the seal, hose routing, or connection.

Quick checks that fix most bottom leaks

• Pull the drawer out and look for water tracks; note whether water starts at the front corners, center, or rear.
• Clean the drawer sealing surfaces and remove any food debris that can hold the drawer slightly open.
• Confirm the drawer closes fully and isn’t blocked by tall dishes or a shifted rack.
• Check the drain hose for kinks, crushing, or a loose connection; replace if damaged.
• Check the water inlet connection for drips; the sealing washer must be in place and the coupling tightened properly.

Installation and plumbing items to verify (common on DishDrawer leaks)

The DS603I is sensitive to hose routing and connection quality. The installation instructions call out several leak-prevention details, including keeping excess drain hose on the DishDrawer side of the support (or trimming to suit), not cutting the inlet hose, and turning the water valve on to check for leaks. Use the DS603I installation guide for the exact routing and connection steps.

Drain setup checklist

• Keep the drain hose supported; do not let cabinet edges pinch it.
• Avoid sharp bends; maintain a smooth curve from the drawer to the drain connection.
• Stay within the specified maximum drain height (commonly 37 1/2 inches for this platform).

Parts that commonly relate to bottom leaks on this model

If you find the leak is coming from a hose or a seal, these model-matched parts are typical suspects:

Leak location	What you’ll usually see	Model-matched part to consider
Under sink or cabinet rear	Drips during drain-out	Dishwasher drain hose 527137
Around heater plate area	Slow seepage, mineral tracks	Dishwasher heater plate seal 525058
Drawer perimeter	Water at front corners	Dr seal kt 527504
Pump area	Leak during wash circulation	Dishwasher pump motor 528042

Why it matters

Even a small bottom leak can damage cabinets and can also cause poor washing or draining if the drawer is not sealing correctly. Finding the exact start point of the water trail prevents replacing the wrong part.
