What does error code E2 mean on a Gledhill StainlessLite cylinder?

Error E2 on Gledhill StainlessLite cylinders indicates a short circuit sensor fault from damaged wiring or internal sensor failure. Turn off the system and isolate from the electrical supply before any inspection. Inspect sensor wiring for damage, particularly where cables pass through tight spaces or near heat sources. Contact a qualified heating engineer to fit a Gledhill-approved replacement sensor.

What does error code 49 mean on a Gledhill A-Class system?

Error code 49 on Gledhill A-Class systems indicates the S4 temperature sensor (DHW outlet) has a short circuit. Turn off the system and isolate from the electrical supply. Check the sensor wiring for damage or pinching. Replace the sensor if wiring is intact. Contact a qualified heating engineer to fit a Gledhill-approved replacement.

What does error code 45 mean on a Gledhill A-Class system?

Error code 45 on Gledhill A-Class systems indicates the S1 overheat sensor has a short circuit. Turn off the system and isolate from the electrical supply immediately. Inspect sensor wiring for damage or moisture. If wiring appears sound, the sensor needs replacing. Contact a qualified heating engineer immediately as this affects safety protection.

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 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.

Why is water dripping from the tundish on my Gledhill cylinder?

Small amounts of water dripping from the tundish during normal heating cycles is expected, as water expands when heated and the pressure relief valve may release a small amount. However, continuous or heavy discharge indicates a fault condition requiring attention.

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.

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.

Can I leave my Gledhill thermal store switched off for extended periods?

Gledhill does not recommend leaving your unit switched off for prolonged periods without draining it. If the water in the copper cylinder remains cool for an extended time, the natural rate of corrosion accelerates, reducing the appliance lifespan. Additionally, if power is off, the pump is not exercised regularly and may seize. If you need to leave your property for several months, have the unit professionally drained.

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.
