Beko DW603 dishwasher

Drain pump not running during/after cycle:
  • During cycle, water seen draining from two overflow pipes (located by front feet)
  • Drain pump does not run between washes/rinses.
  • Inlet and outlet for blockages
  • Checked other pipe connections and for blockages
  • Ran drain pump on bench (runs fine and resistance felt against vanes)
  • Small flap on outlet side of drain pump housing is intact/moving correctly.
Has ran fine for 3.5 years until suddenly not draining. Even checked that its level!!

Your thoughts - please

Is the most likely candidate a faulty main circuit board?

Ps, disconnecting the pump then adding direct power, results in the residual water being drained.
