Product details

The Siemens SN-25M231GB Full-size Dishwasher in white is the best help you can have with your washing up.

Cleaner crockery

With 12 place settings, you'll be able to get more plates, dishes, cups, saucers and cutlery into this fantastically powerful and efficient dishwasher. Enjoy enhanced loading space with the varioFlex rack with folding levels and tines, and load items of different sizes and shapes more easily with this flexible racking system.

Helping make dishwashing easier, the SN25M-231GB Full-size Dishwasher provides a three-stage rackMatic height adjustable top basket, two foldable plate racks in the top and bottom baskets and two foldable cup shelves in the top basket too.

A cycle to suit all situations

There are five wash programmes at your disposal with the Siemens SN25M2-31GB Dishwasher, including Intensive 70 °C, Auto 45-65 °C, Economy 50 °C, Quick Wash 45 °C and Pre-rinse. Choose from four wash temperatures to suit the level of soiling and clean most effectively.

In addition, the varioSpeed setting provides up to 50% faster dishwashing in most cycles, and there's a half load option to clean fewer dishes more economically. Care for fragile kitchenware and glasses with the very gentle cleaning action of the proprietary glassCare System.

Clever features and improved economy

The Siemens SN25-M2-31GB Full-size Dishwasher is equipped with an iQDrive motor for smooth, dynamic performance. A residual drying system helps speed up packing dishes away, and the speedMatic hydraulic system improves performance.

Don't overuse washing up powder with the dosageAssist detergent dispenser, aided by an automatic detergent aware system.

Rated A+ for energy efficiency, the dishwasher is extremely economical and also has less of an environmental impact. The hydroSensor and loadSensor help the appliance to perform by using the least amount of water and energy possible.

Augment your kitchen with a white Siemens SN-25M231GB Full-size Dishwasher and feel those post-meal blues slip away.

Delivery and service

Dishwasher Installation

We can also install your new dishwasher on the day we deliver, for most of the UK. Just add installation at the 'Confirm basket’ page.

Here's what we'll do:
  • Check existing electrical and plumbing connections are safe to use and within 1.5 metres of required location.
  • Disconnect the existing appliance, un-box and check the new product.
  • Connect your new appliance to the electricity, mains water and waste.
  • Test there are no leaks and that the appliance is level and fully operational.
  • Take away your old appliance and packaging to be recycled if requested.

Note: Before we arrive, you will need to make sure access is clear to the area you want your appliance installed, the appliance will fit into the space and that the electrical and plumbing connections are within 1.5 metres.

Home Delivery

The Knowhow service team are here to deliver your product at a time that fits around your schedule. Not only will we deliver it for you but we can install it up for you then take your old product away for free recycling.
Delivery can be arranged Monday to Friday between 7am and 7pm.
Please note next day delivery is not available to this product.

Removed & Recycled for Free
When we deliver your new appliance, we’ll recycle your old one to save you the trouble. Unlike many other retailers it’s completely free and we’ll take away all the packaging too.
Please note that you will need to disconnect your old product before we arrive unless you have purchased installation.
