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.

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 E1 mean on a Gledhill StainlessLite cylinder?

Error E1 on Gledhill StainlessLite cylinders indicates an open circuit sensor fault. The temperature sensor is not connected or has a broken wire. Turn off the system and isolate from the electrical supply before checking any connections. Check all sensor cable connections. If connections are secure, contact a qualified heating engineer to test and replace the faulty sensor with a Gledhill-approved part.

What does error code 40 mean on a Gledhill A-Class system?

Error code 40 on Gledhill A-Class systems indicates the ID resistor has an open circuit. This resistor tells the controller which appliance type is installed. Check the ID resistor connections, and if missing or damaged, contact a qualified heating engineer to fit the correct value resistor for your model.

What does error code 56 mean on a Gledhill A-Class system?

Error code 56 on Gledhill A-Class systems indicates the bottom immersion heater has failed. Turn off the system and isolate from the electrical supply. The bottom immersion heater is the main off-peak heater that heats the entire store. Do not attempt to inspect or replace the heater yourself. Contact a qualified heating engineer to test and replace the immersion heater with a Gledhill-approved part.

Is it normal for my Gledhill cylinder to make noise when heating?

Some noise during heating is normal, as the copper cylinder containing 100-200 litres of water will produce sound when heated, similar to a kettle. Noise typically occurs during overnight heating or when using the boost function. However, if noise levels increase noticeably, become excessive, or you hear unusual banging or foghorn sounds, contact a qualified heating engineer to investigate.

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 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.

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.

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.
