pump over run?

[Chris H]

Replaced a burnt out heating pump, replaced wiring exactly as was on original. Checked it later some 45 minutes after heating clicked off and the pump is still running with programmer not calling for anything. Could this be anything on the boiler (baxi solo 3 pfl). Owner thinks possibly original pump was running 24/7 for sometime as the noise use to keep him awake. Any ideas?
