Dishwasher repair

Leaking exhaust hose (Bosch SMS 5342)

after 10 years of rubbing against the wall when water is pumped out the exhaust hose developed a hole ( appros 2 mm x 1 mm)

the initial repair was by filling the hole with silicone sealant bound down with Duck tape. This lasted approx 8 months. I think it failed because the duck tape was worn away in a similar manner. if doing it again I'd add something to relieve the rubbing ( ?polystyrene block ?)

The generic exhaust hoses from the sheds do not provide a water-tight seal with this model of Bosch dishwasher ( I suspect they don't with any model), even though the inside of the hose looks the same. I needed to order a Bosch-specific replacement.

the hose is held in place by a gripper where it runs through the frame of the machine. I prised it out with a screwdriver adn then removed the old hose. Feed the hose in and mark the position at the outside of the case. Then remove hose, fit gripper and replace. When starting it up it was clear (having gone through 1 cycle and getting stuck with 1 minute to go) that there was no water flowing into the machine.

My attempts with shed-bought exhaust hoses must have led to water getting into the bottom of the machine. Water in the bottom of the dishwasher activates an anti-flood water cutoff so the bottom of the machine has to be drained I turned mine through 90 degrees, anti-clockwise looking from the front with a couple of towels underneath it.

When returned to the normal position, it worked !

SWMBO has taken the old hose to the allotment - something to do with it being the right size for bumble bees to live in.
