What does error code EA 229 or D5 mean on a Worcester Bosch boiler?

Error code EA 229 or D5 on a Worcester Bosch boiler indicates a frozen condensate pipe or loss of ionisation signal.

Do not attempt any repairs involving gas components. If thawing does not resolve the issue, or if you smell gas, do not operate any electrical switches, leave the property and contact a Gas Safe registered engineer from outside.
