Bosch Dishwashers are not as well built or reliable as they were. The picture shows a leak from the sump that drips onto the drain pump motor and then fills the base of the dishwasher giving an E15 fault code and putting the dishwasher out of action.
The most common fault code on a Bosch dishwasher is E24 which should be a drainage problem but I have found the E24 and E25 could be anything from the reed switch to the motor (heat pump)
Tricity Bendix washing machine around 20 years old. Amazing how small washing machine portholes were then. Bit of a struggle getting your bigger heavier items in and out.
