Fisher & Paykel Dishwasher DD603-88445-B FAQs

Yes. On the Fisher & Paykel DD603-88445-B double DishDrawer dishwasher, both drawers operate independently, so you can run wash programs at the same time (including different cycles) as long as each drawer is loaded correctly and started separately. See the DD603-88445-B owner's manual for cycle and option details.

How to run both drawers at once

  • Load each drawer so the spray arm can rotate freely.
  • Add detergent to each drawer you plan to run.
  • Select a wash program on each drawer’s control panel.
  • Press Start/Pause for each drawer.
  • Close both drawers fully so the cycles can run without interruption.

What to expect when both drawers run

Running both drawers simultaneously is normal; it mainly affects total water and power use during that time.

What you notice What it means What to do
Longer or changing time display Wash times are approximate and vary with water temperature and load Use the display as an estimate, not an exact countdown
One drawer finishes first Different cycles and loads finish at different times Unload the finished drawer; let the other continue
More sink hot-water demand Both drawers may draw hot water during fills Run hot water at the sink first if fills seem slow

Tips to prevent performance issues

  • Avoid blocking the drain filter area with utensils or labels.
  • Keep tall items from interfering with the lid seal area when closing.
  • Use the right cycle for the load (Heavy for baked-on soil, Fast for lightly soiled items).
  • If you see a fault, follow the fault code steps in the guide before restarting.

Why it matters

Using both drawers at the same time is one of the biggest advantages of a double DishDrawer: you can wash a small load in one drawer while running a different cycle in the other, which helps with flexibility and day-to-day efficiency.

On the Fisher & Paykel DD603-88445-B DishDrawer, you do not “reset” the flood switch by itself; you clear the fault, remove the water that triggered it, and then restore power. Start by pressing POWER to stop the beeping and clear the code; if it returns, turn power off at the supply, dry the base area, fix the leak source, then power back on (see the DD603-88445-B owner's manual).

What the flood switch fault means

The flood switch activates when water is detected where it should not be (typically the base pan). The dishwasher beeps continuously and shows a fault code until the condition is corrected.

Steps we recommend (safe, practical order)

  • Press POWER once to try to remove the fault code and stop the continuous beeping.
  • If the beeping or code will not clear, turn power off at the power supply (switch or breaker).
  • Turn water supply off at the shutoff valve.
  • Pull the drawer out carefully and check for obvious water, suds, or a loose hose connection.
  • Dry any water you can access; let the unit air-dry if needed.
  • Restore water and power; run a short Rinse cycle to confirm it fills and drains correctly.

Common causes to check (before you run it again)

  • Loose or leaking inlet hose connection
  • Leaking drain hose or drain connection
  • Oversudsing from incorrect detergent (especially hand soap)
  • Drawer not sealing due to a misloaded rack or debris on the seal
  • Water supply or drain routing issues from installation

Quick decision table

What you see What to do next
Fault clears and does not return Run a Rinse cycle and monitor for leaks
Fault clears but returns during fill/drain Recheck inlet and drain hose connections and routing
Fault will not clear with POWER Turn power off at supply, dry base area, then retry

Why it matters

A triggered flood switch is the dishwasher protecting your kitchen from a leak. Clearing the code without removing the water and fixing the leak source usually makes the fault come right back.

For installation-related leak checks (hose routing, drain height, and connection points), use the DD603-88445-B installation guide. If you need to look up diagrams or order replacement items by model number, search by DD603-88445-B on Sears PartsDirect.

Common problems on the Fisher & Paykel DD603-88445-B DishDrawer dishwasher are poor cleaning from clogged filters or spray arm holes, draining problems from a kinked or blocked drain hose, and leaks at inlet or drain connections. Use the installation guide and owner's manual to match symptoms to checks and fault codes.

Most common symptoms and likely causes

  • Water left in the drawer: drain hose kink, blockage, or drain filter packed with debris
  • Dishes not clean: blocked spray arm holes, overloaded drawer, or incorrect detergent amount
  • Leaks: loose hose coupling, missing sealing washer, or poor drain hose routing
  • Long cycles: incoming water temperature and load conditions (cycle times vary)
  • Fault codes: the control detected a fill, drain, heating, or sensor condition

Quick checks we recommend first

  • Reset power at the breaker for 1 minute, then restart.
  • Clean the drain filter, filter plate, and spray arm.
  • Inspect the drain hose for kinks; keep excess hose on the DishDrawer side of the support.
  • Check the inlet hose connection; confirm the sealing washer is installed and the coupling is snug.
  • Run a Rinse program and confirm it fills, sprays, then drains completely.

Installation items that cause repeat issues

The DD603-88445-B is sensitive to hose routing and sealing. Confirm these points in the installation guide.

Problem area What you notice What to do
Drain hose routing Slow or no drain Re-route, remove kinks, support hose properly
Inlet hose seal Drips at valve or inlet Install sealing washer, tighten, recheck
Excess drain hose length Odd draining behavior Keep excess on unit side or trim to suit

Why it matters

Fill, drain, and spray issues cause dirty dishes, standing water odors, and cabinet damage from leaks. A short filter and hose inspection prevents most repeat faults.
