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 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 E1 mean on a Gledhill A-Class system?

Error E1 on Gledhill A-Class systems indicates an open circuit sensor fault, meaning a temperature sensor wire is broken or disconnected. Turn off the system and isolate from the electrical supply before checking any connections. Check the sensor cable connections at both the sensor and controller. If connections appear secure, contact a qualified heating engineer to test and replace the faulty sensor.

What does error code 52 mean on a Gledhill A-Class system?

Error code 52 on Gledhill A-Class systems indicates the S2 overheat sensor has a short circuit. This is a safety-critical fault. Turn off the system and isolate from the electrical supply immediately. The sensor must be inspected and replaced promptly. Contact a qualified heating engineer to replace with a genuine Gledhill overheat sensor.

What does error code 43 mean on a Gledhill A-Class system?

Error code 43 on Gledhill A-Class systems indicates the S6 temperature sensor (store middle) has an open circuit. Turn off the system and isolate from the electrical supply. Inspect sensor wiring for damage. If wiring appears intact, the sensor is likely faulty. Contact a qualified heating engineer to replace with a Gledhill-approved sensor.

What pressure should the expansion vessel on my Gledhill cylinder be set to?

The air side of the expansion vessel should be set to 3 bar. This must be checked when the system is depressurised and the water is at atmospheric pressure.

Do I need a scale inhibitor for my Gledhill cylinder in a hard water area?

In areas where water hardness exceeds 200 parts per million (ppm), Gledhill requires appropriate treatment of the incoming cold mains water supply to prevent scale build-up. This may include installation of a water softener or scale-inhibiting device. Failure to install adequate water treatment in hard water areas can impair performance, reduce appliance lifespan, and may affect your warranty coverage.

What should I do if my Gledhill cylinder goes into overheat lockout?

If your cylinder enters overheat lockout, first turn off all heat sources and allow the system to cool completely before attempting any reset. Do not tamper with safety valves or overheat thermostats. If hot water is discharging, turn off the heat source immediately. Some models have a manual reset button on the thermostat, but the cause of the overheat must be investigated by a qualified heating engineer before resetting to prevent recurrence.

What is the minimum water pressure required for a Gledhill StainlessLite Plus?

For optimum performance, 3 bar pressure and a flow rate of 30 litres per minute is recommended. The appliance will work with lower pressures, however performance will decrease with low flow rate and low pressure.

Are Gledhill cylinders compatible with solar thermal panels?

Yes, Gledhill produces the Torrent SOL range specifically designed for use with solar thermal panels. These models feature a high-efficiency solar coil and can work alongside conventional boilers, providing mains pressure hot water. When solar energy is insufficient, the system automatically reverts to the boiler as the primary heat source. A backup immersion heater is also included for emergency use.
