Bosch Exxcel Dishwasher for spares or repair (Sharmans Cross B91)

Bosch Exxcel model SMS65E02UK/01 full size freestanding white dishwasher - faulty. 15 years old but household is 2 adults so possibly used less than for a family. Wasn't filling with any water; now fills but water only trickling out of rotor arms - not enough to move them. I've checked filters. Might be heat/circulation pump - available form espares at £145 - other retailers stock what looks similar significantly cheaper but won't confirm it fits this model.

TRANSPORT REQUIREMENTS: heavy - weight possibly > 50kg. Step free access so could be moved on a trolley (we have a ramp to our front door). Should be kept upright because although I've drained the appliance there may be residual water.
