DW ia a fully intergrated full sized Bosch , had it 4 years and used daily , often 2-3 times a day.
It's now decided not to heat 
So it will wash (after a fashion) but no hot water and no heat to dry.
Out of warranty so we'd need to find a repairer. Is it worth it or replace it? It's gone wrong before when in warranty , no water was going in, they replaced a little 'float 'sensor .
Any advice?
