What does error code 10 mean on a Gledhill A-Class system?

Error code 10 on Gledhill A-Class systems indicates an overheat lockout. The system has detected dangerously high temperatures and entered safety lockout. Turn off the heat source immediately and allow to cool before attempting reset. If the fault recurs, contact a qualified heating engineer to diagnose faulty sensors or valves.

What does a slow flashing red light mean on a Gledhill PulsaCoil A-Class?

A slow flashing red light (once per second) on Gledhill PulsaCoil A-Class may indicate the unit has cooled and can be reheated using the On Peak Boost button, or it may indicate immersion heater element failure or burnt-out power relay. Try the boost button first; if no improvement, contact a qualified heating engineer.

What does error code 51 mean on a Gledhill A-Class system?

Error code 51 on Gledhill A-Class systems indicates the S6 temperature sensor (store middle) has a short circuit. Turn off the system and isolate from the electrical supply. Check sensor wiring and connections. If intact, the sensor requires replacement. Contact a qualified heating engineer to fit a genuine Gledhill replacement sensor.

What does error code E3 mean on a Gledhill A-Class system?

Error E3 on Gledhill A-Class systems indicates a sensor is reporting a temperature greater than 99°C. Turn off the heat source immediately and allow the system to cool. Do not use hot water until cooled below 60°C. Contact a qualified heating engineer to investigate the cause before resetting.

What does error code 33 mean on a Gledhill A-Class system?

Error code 33 on Gledhill A-Class systems indicates an appliance selection error where the controller settings don't match the ID resistor fitted to the unit. Contact a qualified heating engineer to verify and correct the appliance selection settings or fit the correct ID resistor.

What warranty comes with a Gledhill cylinder?

Warranty coverage varies by product type: unvented cylinders receive 25 years on the cylinder plus 2 years on components; open vented cylinders receive 10 years on the cylinder plus 1 year on components; thermal store appliances receive 5 years on the cylinder plus 1 year on components.

What temperature should my Gledhill cylinder be set to?

Gledhill cylinders should be set to achieve a minimum of 60°C to 65°C. This temperature needs to be achieved regularly to comply with legionella pasteurisation requirements and prevent the growth of harmful bacteria.

Why are my Gledhill PulsaCoil electricity bills high?

High electricity costs are virtually impossible if the unit is correctly installed and used properly, as units should only heat during off-peak periods unless you manually use the boost function. Check that your boost switch is off and your timer is correctly set to your off-peak hours.

Are Gledhill cylinders compatible with heat pumps?

Yes, Gledhill produces the StainlessLite Plus Heat Pump range specifically designed for use with air source or ground source heat pumps, providing mains pressure domestic hot water.

Why don't Gledhill thermal stores need legionella pasteurisation cycles?

Gledhill thermal stores heat mains water instantaneously as it passes through a plate heat exchanger, rather than storing domestic hot water. Since the tap water is never stored within the appliance and is heated on demand, there is no standing water where legionella bacteria could multiply. This design eliminates the need for high-temperature pasteurisation cycles required by traditional stored hot water cylinders.
