Baxi Error Codes

Question

What is the meaning of the Baxi Error Codes E28 and E133?

Andrew · Answer

Those error codes refer to the condensate pipe, check you have no blockages .
Start by tracing the white pipe under the boiler it should run internally to the waste pipe normally under the kitchen sink.
Hold a bucket underneath, put plug in sink discover condensate pipe check for blockages. Use wet vacuum to suck all stuffs out of other connecting pipes or take outside to garden hose tap & clean out, connect all pipework back flush condensate pipe by running the central heating for 10 - 15mins make sure it doesn't lock out to the same error codes.

Jamie · Answer

Condensate pipe may be blocked by something. 
Check the end for blockages.

Edwin Moris · Answer

If there us an error code reading E23 or E133 on a baxi boiler. It may be one of the following; condense trap may be block or the condensate trap is frozen.

Wayne · Answer

Normally to do with a blocked condense pipe. Sometimes the boiler will come on for a short while before locking out

Jim · Answer

Usually means a frozen condensate pipe!!!! 

Is the condensate pipe or trap blocked?

Ahmed · Answer

The meaning of two codes errors it means your boiler condensation pipe may be frozen in this case you have to defrost the frozen condensation pipe do not use boiling water straight way from kettle is this could damage your pipe after turn on the power at boiler and restart the boiler should works

Jeffrey · Answer

Boiler has shut down in error code try resetting boiler if doesn't work you'll need a engineer.

Alan · Answer

Many points one main one is gas ignition failure,  locks out  could be gas valve, rectification of flame failure back to board

Dave · Answer

Hiya Lauren E133 and E28 refer to frozen condense pipe which in this weather is highly unlikely I reckon it’s blocked with sludge it’s a easy repair for a heating engineer

Stuart · Answer

E133 is no gas / gas valve / generator/. Electrode
E28 flue thermistor 
Gas engineer required to repair

Scott · Answer

E133 is an ignition fault either the fan or gas valve

Mal · Answer

You probably have a blocked condensate trap. Boiler will need servicing

Andy · Answer

Hi E28 is a flue thermistor fault and E133 is failure to light.

Jack · Answer

Ignition fault

Could be electrodes arking or flame not being sensed does the boiler ignite.if it does then I’d say that’s your issue if not could be gas valve or blocked Venturi
