Gledhill Appliance Repair in St David's

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 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 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 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.

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.

How does the Economy 7 system work with my Gledhill PulsaCoil?

Economy 7 provides electricity at about half the normal price during the seven hours between midnight and 7am. Your PulsaCoil heats a full tank of water overnight using this low-cost electricity to last you throughout the day.

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.

Where can I find the serial number on my Gledhill cylinder?

The 12-digit serial number for unvented cylinders and thermal stores is printed underneath the bar code on the data label or information badge located on the appliance. The first and last digits are spaced slightly away from the rest of the number.

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.

Should I choose copper or stainless steel for my Gledhill cylinder?

Stainless steel is recommended as the superior option when considering durability and reliability, particularly for unvented systems. While copper has excellent heat conductivity, stainless steel has much higher resistance to all forms of corrosion and can withstand higher pressures.
