What Does Error h04 Mean?

The Neff Dishwasher error code H04 indicates that the appliance is in a delay start mode rather than a fault condition. This code appears when the machine is set to wait for a preselected delay before starting a wash cycle, which may be accompanied by the display showing H followed by a number. If no additional error lights are present, the dishwasher will begin operation once the delay time elapses.

Common Symptoms:

  • Display shows H followed by a number and machine does not start immediately
  • No additional error lights (like water, faucet, or alarm icons)
  • Dishwasher waits for the preselected delay time before starting

Possible Causes

  • Delayed start / time preselection active (medium)
