Dishwasher will not start and immediately attempts to drain, often continuously, with F15 indicated. This is commonly linked to water in the base tray.

Safety: Disconnect power and turn off the water supply. Be prepared for water when tilting the appliance.

Drain the base tray:

• Carefully pull the dishwasher out from under the counter.
• Gently tilt it backwards about 30–45° to allow water in the base tray to run out onto towels or a shallow tray.
• Leave the machine tilted for several minutes to ensure the float switch drops back down.

Locate the leak:

• Remove the lower front or side panels to inspect the base while running a short fill cycle (use caution around live parts; only a competent person should do live leak checks).
• Look for drips from the sump, circulation pump seal, drain hose, inlet valve, or door gasket.

Common fixes:

• Tighten loose hose clamps and replace any cracked hoses.
• Replace a perished door gasket if water is seen leaking from the front.
• If the plastic sump is cracked or the pump seal is leaking, replace the affected component.

Do not bypass the anti‑flood float switch; always correct the underlying leak before further use.
