my worcester bosch 40 cdi boiler has error code SE or 5E, after low pressure. Can anyone tell me what this means?

It has also had two T's on their sides which i understand to be a system check. It seems to be ok at the moment but am worried what the SE or 5E means?

Can anyone help at all?

Many thanks in anticipation

It just means that it's due for a service - this code shows after the burner has been run for 2324 hours. To manually reset the display, follow the steps at http://www.worcester-bosch.co.uk/cache/file/239/guide-to-re-setting-the--se--code-on-greenstar-cdi-boilers.pdf

se means you need a service

This is a symbol indicating the need for the boiler to be serviced due to the run hours used.

Reseting requires a series of operations following the service.

the SE code is not a fault, it just means that a (SE) service engineer needs to call and do an annual service, it usually shows up every two years if it has not been reset at the service visit , you need to get a corgi engineer to service and/or reset the service setting / he can ring worcester for the procedure (neither are shown in any instructions).

the 2 sideway T shapes show when the electric has been turned off and back on again, they usually show for about 15 mins ,the onboard electronics think it is starting from new and are filling the condensate trap, any longer than may need a new pcb check with worcester
