Common Baxi 600 Faults

E01 — Ignition Lockout

The most common callout on the Baxi 600 across London. The boiler attempted to ignite and the flame did not establish within the ignition period. On a 600 that has not been serviced, electrode wear is the primary cause. We carry the ignition electrode for all Baxi 600 outputs and replace it on the first visit. A full service at the same time keeps the boiler running well for another year.

E119 — Low Water Pressure

Low pressure lockout. The Baxi 600 filling loop is usually a flexible silver hose under the boiler with two valves. Open both slowly to 1.2 to 1.5 bar on the gauge and close. Reset the boiler. If pressure keeps dropping, call us to find and fix the system leak.

E110 — Overtemperature

The boiler has overheated. In London’s hard water areas this is frequently caused by scale restricting flow through the heat exchanger. On a 600 in a hard water area without a scale reducer, we start to see E110 faults from around five to seven years old. We assess the heat exchanger condition and advise on descaling or replacement as appropriate.
