What to do if the Morco Water Heater burner does not switch off?
- R
  Regina MarquezAug 1, 2025
  If the burner on your Morco Water Heater doesn't switch off when the water is turned off, it could be due to contamination on the gas valve seat, which requires testing and cleaning. Another potential cause is a gas valve push rod locked in the open position; in this case, check the cold water push rod's operation, and dis-assemble, clean, or replace if necessary. Also, check the gas pressure; if it exceeds the specified limit, replace the pressure regulator on the external bottle or tank.

Why pilot on but the main burner does not ignite on my Morco EUP11 Water Heater?
- T
  Tina StevensAug 5, 2025
  If the pilot light is on but the main burner of your Morco Water Heater doesn't ignite, the issue might be due to insufficient water pressure. Try to increase the external water supply pressure. Alternatively, the diaphragm could be broken, requiring a replacement.

  Donna AdamsAug 9, 2025
  If your Morco Water Heater isn't sparking, it could be due to a disconnected spark wire; reconnect it. Another possibility is a broken piezoelectric mechanism, which would need testing and replacement. Finally, the electrode might be damaged, and you would need to replace it.

Why the pilot does not switch on when there is a spark in Morco EUP11 Water Heater?
- R
  Robert CookAug 18, 2025
  If the pilot light on your Morco Water Heater doesn't switch on even when there's a spark, it could be due to a blocked pilot injector; clean it by immersing it in solvent or replace it. Another reason may be that the electrode activation position needs adjustment. Also ensure that there is a gas supply and open the appliance gas isolation valve. Finally, purge air from the gas tubes by turning on all gas rings on the hob for 30 seconds.

Why the heat exchanger fins becomes sooty in a small amount of time in Morco EUP11?
- C
  carolyndanielsAug 22, 2025
  The heat exchanger fins becoming sooty quickly in your Morco Water Heater can be caused by several factors. It may be due to poor draught, adverse weather conditions, or dusty surroundings; in this case, check the flue installation. A yellow flame could also be the culprit, so check the gas type and clean the burner. Finally, excess gas consumption might be the issue; check the gas pressure and adjust accordingly.

Why Morco Water Heater has a delayed burner activation?
- X
  xjohnsonAug 27, 2025
  A delayed burner activation in your Morco Water Heater may occur if the pilot burner flame is too far from the main burner flame or if it is too short. To resolve this, check the inlet gas pressure and clean the injector and pilot burner.
