Gledhill Appliance Repair in Exwick

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

A fast flashing red light (four times per second) on Gledhill PulsaCoil A-Class indicates the control board has detected a potential overheat. Turn off and isolate the appliance from the electrical supply immediately. This can indicate actual overheating or a faulty control board. If you smell burning, evacuate and contact emergency services. Otherwise, contact a qualified heating engineer to diagnose the issue.

How often should I check the header tank on my Gledhill thermal store?

Gledhill advises checking the header tank water level every three months. The tank should be filled with clean cold water to approximately halfway. Do not overfill as this can cause problems. Ensure the lid is securely replaced to reduce water loss through evaporation. Some units have an optional sight glass fitted to make checking the level easier.

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.

Is the hot water from my Gledhill thermal store safe to drink?

Yes, the hot water delivered through your taps is your mains cold water which has been instantaneously heated by the appliance, ensuring drinking-quality output without stored water exposure.

How long does a Gledhill cylinder last?

This is heavily dependent on the quality of installation, the way the appliance has been used over the years, and the quality of maintenance and care it has received. With proper maintenance, Gledhill unvented cylinders are backed by a 25-year manufacturer warranty.

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.
