It is possible to run a dishwasher on board your narrowboat providing you can generate sufficient power; either by shoreline, inverter or generator. Space, power generation & water consumption will be the main factors in deciding if a dishwasher can be accommodated on-board a narrow boat.

Compact 55 x 50 x 45 40-60 items 2400 6.5

* Litres per standard cycle


  • Energy consumption on a canal boat with no shoreline power is a major consideration.
  • There is no energy saving by opting for a smaller model, the only advantage is the space savings.
  • A standard wash cycle may take over 2 hours to complete which is a consideration for using on a canal boat if you are not on shoreline power.
  • Many models will have an eco-programme which will reduce the water and energy consumption but increase the cycle running time, which is not ideal on a canal boat without shoreline power.
  • Many dishwashers also offer a half load option for a quicker solution.
