    "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."

    "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"

    "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"
