Bosch E18 is a water flow problem: the water level is too low, or water is not being pumped correctly. It is not the inflow-only pair E16 / E17. E18 has two checks. First, the inlet hose must not be kinked or damaged, which is the same hose look E16 / E17 stops at. Second, the water supply has to be turned on. Bosch states the required flow as 10 l/min. That flow number is not on the E16 / E17 page. If E18 remains after both checks, contact Bosch Customer Support.
Likely causes
- Kinked or damaged inlet hose
- Water supply turned off or too low
How to fix E18: safe DIY steps
- Check the inlet hose and make sure it is not kinked or damaged
- Make sure the water supply is turned on (Bosch gives the required flow rate as 10 l/min)
Capacitors can hold a charge after the power is off. Safety terms.
