CE

System pressure too low

The boiler reports that central-heating system pressure is below the required level.

What this code means

The boiler reports that central-heating system pressure is below the required level.

Possible causes

  • Low system water pressure
  • Water loss from heating system
  • Recent radiator bleeding
  • Leak or expansion-related issue

Common symptoms

  • CE displayed
  • Heating may stop
  • Pressure gauge or display shows low pressure

Checks to make

  1. Check the boiler pressure display or gauge
  2. Follow the appliance user instructions for repressurisation if appropriate
  3. Check for visible leaks
  4. Arrange service if pressure repeatedly drops

Safety

  • Do not remove the boiler casing. If pressure repeatedly falls, the underlying cause should be investigated by a competent heating engineer.

Model notes

The cited Worcester Bosch technical literature maps CE to low system pressure.
