Is the Bosch Series 4 WAN28259GB worth it?
Yes, if you want a reliable 9 kg machine without extras.
It's a 9 kg, 1400-spin Bosch with an A energy rating, a quiet spin, SpeedPerfect to shorten cycles, Iron Assist and Reload to add a forgotten sock, and Bosch's 5-year guarantee when you register it. It's simpler and cheaper than the Series 6 WGG24400GB, without the stain programmes. Owners mostly praise how quiet and easy it is. The few complaints are long programmes, quick washes that leave clothes wet, and controls that take learning. No independent test we can read has been published, so this verdict rests on Bosch's specs and verified owner reviews.

What owners say
Owners love how quiet and easy to use it is. The few complaints are long programmes and wet clothes after short washes.
Good to know

- The main programmes are long; Eco 40-60 runs for nearly four hours.
- Some find the controls and the manual confusing at first.
- A few mention water left in the door seal after a wash.

How we reached this verdict
No independent test we can read has been published: Which? has tested it, but its verdict sits behind a paywall. The specs come from Bosch UK: 9 kg, 1400 rpm, A energy class, spin-drying class B, 72 dB on the spin, 59 cm deep, SpeedPerfect, Iron Assist, Reload, Hygiene Plus and Active Water Plus, with a 5-year guarantee on registration. The Currys pool (Currys, AO and other shops) has over 1,500 verified owner reviews of this 9 kg model, and only 26 rate it 3 stars or less. Owners most often praise how quiet it is and how easy it is to use; the unhappy ones mention wet clothes after short programmes, long cycles, confusing controls and a few early faults.
We compared independent expert reviews with the manufacturer's specifications, then checked it's sold at a major retailer where you live. We don't test products ourselves.
