What Does Error h01 Mean?

The Siemens Dishwasher error H01 indicates that the delayed start timer is activated, meaning the dishwasher will not begin its wash cycle until the specified time has elapsed. This is not a fault but a feature that shows a countdown on the display. If you see H01, your dishwasher is scheduled to start after a delay. To resume normal operation, adjust the timer to H00, allowing for immediate start to your desired wash program.

Common Symptoms:

  • Dishwasher does not start immediately
  • Display shows "H01" or similar (e.g., H12, H24)
  • Cycle begins only after the indicated delay time

Possible Causes

  • Start time delay (delayed start) is active (high)

How to Fix Error h01

DIY Fix Cancel delayed start

  1. Look at the dishwasher control panel where 'H01' is displayed.
  2. Use the plus/minus or delay buttons to reduce the number until 'H00' appears.
  3. Once 'H00' is set, start your chosen wash program normally.

Technician Only Verify control/display functionality (if unexpected)

  1. Confirm that the dishwasher responds to controls normally.
  2. Check that no unrelated error codes appear.
  3. If display input seems unresponsive or erratic, inspect control panel ribbon connections.

Parts needed: Control panel assembly, Ribbon/display interface

🛑 When to Call a Pro:
  • If the dishwasher fails to respond to control inputs entirely or shows separate E‑style error codes.
  • If the display shows unexpected symbols in addition to H01 that do not clear when adjusting the delay timer.
