Getting to a dealer from Borehamwood usually means a recovery movement, so the sequence matters: drain and flush first, establish whether the system has latched, and only then decide whether a dealer visit is unavoidable. A mixed fleet around Borehamwood means a mixed set of failures: nozzle errors on the commercial side, bottle errors on the domestic side, and quality faults from bulk tanks on both.

None of the local detail changes the verdict: the direction of contamination decides what is recoverable, and the postcode does not.
