Miele Dishwasher Error F24: Circulation Pump Malfunction or Heater Relay Error

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The dishwasher has detected a malfunction in the circulation pump or a fault in the heater relay on the control board. The circulation pump moves water through the spray arms during the wash cycle — if it fails, dishes will not be washed.

Severity

High - stop using the Miele dishwasher until the cause is understood or professional help is arranged.

Can you fix it yourself?

No — call a technician

Most likely cause

Circulation pump motor failure — the pump motor has seized or burned out

Estimated time for safe first checks: Professional service required.

Step-by-Step DIY Fix Guide

  1. SAFETY: Disconnect power at the wall outlet.
  2. Perform a power cycle: unplug for 60 seconds, then plug back in.
  3. Run a short test cycle — if F24 returns, contact Miele service.
  4. Do not attempt to access the circulation pump yourself — it is located beneath the wash tub and requires full disassembly.

If the airflow problem comes back

  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • F24 returns after a power cycle

What This Error Means

Error F24 on your Miele dishwasher means: The dishwasher has detected a malfunction in the circulation pump or a fault in the heater relay on the control board. The circulation pump moves water through the spray arms during the wash cycle — if it fails, dishes will not be washed. The dishwasher's self-diagnostic system has detected this condition and stopped or interrupted the current cycle.

The most frequent cause is circulation pump motor failure — the pump motor has seized or burned out. Work through the causes and fix steps below in order — many Miele dishwasher errors can be resolved without a service call.

Miele classifies F24 as a technician-only fault. A power cycle is the only DIY step — if the code returns, contact Miele service.

On a brand-new Miele dishwasher, adding 1 litre of water to the tub before the first cycle primes the circulation pump and prevents dry-run faults. If F78 appears on first use, this is almost certainly the cause.

Most Likely Cause by Symptom

The Miele dishwasher may stop, pause, or refuse to complete the cycle normally.

Likely cause: Circulation pump motor failure — the pump motor has seized or burned out

Check first: SAFETY: Disconnect power at the wall outlet.

The warning may return immediately because the appliance is detecting an internal fault.

Likely cause: Heater relay fault on the main control board — the relay controlling the heating element has failed

Check first: Perform a power cycle: unplug for 60 seconds, then plug back in.

Common Causes

  • Circulation pump motor failure — the pump motor has seized or burned out
  • Heater relay fault on the main control board — the relay controlling the heating element has failed
  • Foreign object in the circulation pump impeller jamming rotation

What Not to Do

  • Do not run repeated cycles hoping F24 will clear — a failed circulation pump will not recover without replacement

Model and Display Variation Notes

Model-family notes

  • Miele dishwasher display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Service option

Miele service visit if the warning returns after the basic checks are complete.

Manual and model check

Check your exact model and manual before ordering any Miele dishwasher parts.

Common parts

  • Circulation pump if pump motor has failed ($80-$180)
  • Main control board if heater relay has failed ($150-$350)

This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.

When Not to Keep Troubleshooting

F24 returns after a power cycle

How to Prevent It Recurring

  • Always scrape food debris from dishes before loading — hard particles can enter the circulation pump and cause premature failure
