Why does my Bosch Sensixx DS38 make a pumping sound?
- RRobert JordanSep 6, 2025
Your Bosch Iron may make a pumping sound because water is being pumped into the steam tank, or the water tank is not fitted onto the housing correctly. Fit the water tank back onto the housing correctly. If the sound will not stop, do not use the steam generator and contact an authorised technical service centre.
