Do you own an SRE 300 Model Inverter Heater. This product is known by several different brands such as Kero and Ruby, it is a very popular model in Italy & France and is distributed throughout the UK and Europe by Brico Bravo.
The SRE 300 Model is sometimes also sold as SRE301 and SRE 4600 and the error codes on this page apply to all of these models.
If your SRE 300 inverter heater is used on a regular basis, then at some point you will probably experience a random problem with the heater, where it will fail to ignite, or simply cut out after a period of operation.
The SRE Heaters, are fitted with many safety and monitoring devices, and if these sensors trigger a fault, then the inverter heater will cut out and an error code will display on the lcd screen on the front panel. On the SRE 300 / SRE 301 and SRE 4600 these error codes are displayed as either a letter “E” or “D” followed by a single digit – eg E7
