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
