Working dishwasher for charity shop (Amersham HP7)

Our much-used dishwasher at Amersham Owned has died and I wonder if anyone has a full-size, working dishwasher they no longer need and would donate to us? The shop in the old Laura Ashley building is part of The Hospice of St Francis, and we use the dishwasher daily to clean donated china, glassware and also teacups as used by staff and our lovely volunteers. We can of course collect it and would be very grateful.
