My folks had the BOL Hotpoint dishwasher from 1989. The machine lasted for about 15 years or so! It got put on after every dinner and it fell into my good hands to unload it before I went to School. This is why we got a Bosch dishwasher since the racks have not really changed a great deal.
I think the model number for my dishwasher was 7821. It had three programs: Super wash 65(written in Red), Normal wash 65 (written in green) and Pre Wash no heat (written in white). It had that perspex cover too so the machine looked as good as new even when it was ready to go to the skip! What killed it was a leak that went undetected and rusted the bottom off it. It was tripping the circuit breakers. It was replaced by another Bosch made Hotpoint. The DWF34. Thinking back now, the machine is pretty much identical to the Bosch machine I have now.
