Fisher & Paykel DD603-88270 dishwasher Parts

Yes. On the Fisher & Paykel DD603-88270, each DishDrawer has its own control panel and can run independently, so you can run both drawers at the same time on different wash programs (as long as each drawer is loaded and started normally). See the DD603-88270 user manual for operating details.

How to run both drawers successfully

• Load each drawer so items do not protrude above the top edge (this helps the lid seal correctly).
• Add detergent to the dispenser for each drawer you plan to run.
• Select a wash program on each drawer’s control panel.
• Close each drawer fully, then press Start on each drawer.
• If a fault occurs, check the fault code section and correct the issue before restarting.

What to expect when both drawers run

When both drawers are running, you can treat them like two separate dishwashers sharing the same water and drain connections.

What you want to do	Recommended approach	Why it helps
Wash mixed loads	Run different cycles in each drawer	Matches soil level and load type
Wash lots of cups/glasses	Consolidate racks and run one drawer	Frees the other drawer for plates/pots
Avoid leaks or poor washing	Keep items below the rim and close drawers firmly	Supports proper lid sealing and spray arm rotation

If one drawer runs but the other will not start

• Confirm the drawer is fully closed.
• Cancel and reselect the wash program.
• Check for loading issues that could prevent sealing.
• Verify water supply and drain connections are not leaking.
• Follow the troubleshooting guidance in the DD603-88270 installation guide if the issue appears right after installation.

Why it matters

Running both drawers at once is one of the biggest advantages of a double DishDrawer design; it lets you wash small loads efficiently or run two different cycles simultaneously without waiting.

On the Fisher & Paykel DD603-88270 DishDrawer, an A3 error points to a flood condition (water detected where it should not be). We fix it by stopping the cycle, shutting off power and water, drying the base area, then correcting the cause (most often a leak, oversudsing, or a drain issue). Refer to the DD603-88270 user manual for the fault-code steps.

Safe reset steps (do this first)

• Press POWER to clear the fault.
• If the beeping or code will not clear, turn power off at the outlet/breaker.
• Turn water supply off at the shutoff valve.
• Pull the drawer out and check for standing water, then dry any visible water.
• Restore power and run a short Rinse cycle to confirm it fills and drains normally.

What usually causes an A3 (and what to check)

• Drain hose problem: kinked hose, blocked hose, or a high loop/route issue that slows draining.
• Leak at a seal or connection: water dripping into the base can trigger the flood switch.
• Oversudsing: too much detergent or the wrong type can foam and push water where it should not go.
• Spray arm obstruction: items blocking rotation can cause poor wash and unusual water movement.

If you find a damaged or kinked drain line, replacing the dishwasher drain hose 527137 is a common repair.

Quick checks that prevent repeat A3 faults

• Confirm the drain hose is not crushed behind the cabinet and has a smooth bend.
• Verify the drain setup stays within the installation limits (including maximum drain height).
• Use only automatic dishwasher detergent; avoid hand dish soap.
• Clean the drain filter and confirm the drawer closes fully and seals evenly.

Troubleshooting guide

What you notice	Most likely issue	What to do
Water in the cabinet base area	Active leak or oversudsing	Dry base, then inspect seals, hoses, and detergent use
Drawer will not drain well	Kink/blockage in drain path	Straighten hose, clear blockage, replace hose if damaged
A3 returns quickly after reset	Ongoing leak or flood switch still wet	Leave power off, dry thoroughly, then re-test with Rinse

Why it matters

A3 is designed to protect your kitchen from water damage. Clearing the code without fixing the leak or drain restriction usually brings the fault back during the next fill or drain.

If your Fisher & Paykel DD603-88270 DishDrawer dishwasher is not draining, we focus on the most common causes: a blocked drain filter or filter plate, a clogged or kinked drain hose, or a spray arm and sump area packed with debris. Start with cleaning and a quick drain-path inspection using the DD603-88270 owner's manual.

Quick checks that fix most no-drain problems

• Cancel the cycle and let the unit attempt to drain again.
• Remove the basket and clean the drain filter so it sits flush with the filter plate.
• Remove and rinse the spray arm; shake out any foreign material.
• Check the drain hose routing for kinks, crushing, or a high loop that is too high.
• Verify the sink/disposer connection is clear (a blocked disposer inlet is a common cause).

Clean the filter plate and drain filter (model-recommended maintenance)

Food scraps can accumulate even with normal use. For the DD603-88270, cleaning the drain filter, spray arm, and filter plate about once a month is typical.

What we do:

• Lift and remove the drain filter, empty it, rinse under running water, and reinstall it.
• Release and lift the filter plate (turn the outer ring counter-clockwise about 1/8 turn), wash it in hot soapy water, then reinstall it flat.

Drain hose and installation limits that affect draining

A drain hose that is routed incorrectly can prevent proper draining.

Item to check	What to look for	Why it can stop draining
Maximum drain height	Keep drain height within the specified limit	Too much lift can overwhelm the drain pump
Hose condition	No kinks, clogs, or crushing	Restricts water flow
Extension length	Do not exceed the allowed extension limit	Excess length increases resistance

For installation routing details (including maximum drain height guidance), use the DD603-88270 installation guide.

Parts that commonly relate to draining issues

If cleaning and hose checks do not restore draining, a worn seal or a damaged hose can contribute to leaks or poor flow.

• Drain hose 527137: replace if split, soft, kinked, or internally clogged.
• O-ring, 4-pack 525940P: replace if you see seepage at connections you disturbed during cleaning.

Why it matters

A DishDrawer that cannot drain will often leave dirty water in the tub, trigger beeping or fault behavior, and can lead to odors. Keeping the drain filter and filter plate clean protects the pump and restores normal wash performance.

On the Fisher & Paykel DD603-88270 DishDrawer, a flood switch fault is not a simple “reset”; it is triggered by water in the base. We reset it by stopping the leak source, drying the base area, then restoring power so the control can clear the fault per the DD603-88270 owner's manual.

What to do first (safe shutdown)

• Press POWER to stop the beeping and clear the display if it will respond.
• Turn power off at the outlet/breaker if the fault returns immediately.
• Turn the water supply valve off.
• Do not run another cycle until the leak source is addressed.

Clear the flood switch condition (what actually “resets” it)

The flood switch clears after the water that activated it is removed.

• Pull the drawer out carefully and look for standing water, drips, or wet insulation.
• Dry any visible water; allow time for the base to fully dry.
• Check common leak points: inlet connection, drain hose routing, lid seal area, and oversudsing.
• Restore power, then turn the unit back on; if the beeping and fault code return, treat it as an active leak.

Common causes to check on DD603-88270

What you notice	Likely cause	What to check
Water under the unit	Hose or connection leak	Inlet and drain connections, clamps, kinks
Water in/around drawer edges	Lid sealing issue	Drawer closing, lid area, debris
Suds or foam	Wrong detergent or too much	Use dishwasher detergent only, reduce amount
Poor draining then leak	Drain restriction	Drain hose routing and sink/disposer connection

If you find a damaged drain line, replacing the dishwasher drain hose 527137 is a common fix when the hose is split, kinked, or leaking.

Why it matters

A flood switch is designed to prevent continued filling and protect the dishwasher and surrounding cabinetry. Clearing the fault without fixing the leak usually brings the fault right back.
