1. 1

   Check if the Heater Can Start

   Turn on the hot water tap fully.

   • Heater tries to start but shuts off
   • Heater does not start at all
   • E1 error appears on the display

   This usually means the heater cannot ignite properly.

2. 2

   Check Gas Supply

   Make sure gas is available.

   • Check if your gas stove is working
   • Ensure the gas valve is fully open

   If gas supply is normal, the issue is likely inside the heater.

3. 3

   Reset the Heater (Once Only)

   • Switch off the power to the heater
   • Wait about 30 seconds
   • Switch it back on and try again

   If the E1 error comes back, do not keep resetting.

4. 4

   Listen for Ignition Sounds

   Stand near the heater when turning on hot water.

   • No clicking sound → ignition not starting
   • Clicking but shuts down → ignition not stable

   Both are common with E1 error code.

5. 5

   Look for Signs of Age or Damage

   Without opening the heater, check outside:

   • Rust around the casing or pipes
   • Heater is old and has had repeated faults

   These often point to internal ignition-related problems.

⚠️ Important: Do not open the heater or touch gas parts.
