A large number of modern washing machines have been designed in a way that can make them so costly to repair, it can outweigh the cost of a brand new machine – or as near as makes little difference.
A Which? investigation has found that a vital part of the washing machine, the bearings, are being sealed away where repairers cannot access them should they fail.
Bosch, Beko, Indesit, Hotpoint, Indesit, AEG and Zanussi all make machines that have sealed drums – and some of these manufacturers have confirmed they only make washing machines with sealed drums.

Sealed washing machine drums
To see how widespread the problem is, we took apart a selection of modern washing machines from major brands Bosch, Beko, Indesit, Miele, Hotpoint, Indesit, AEG and Zanussi. We also took apart thee machines from the 1980s and 1990s, to see how washing machine design had changed over the years.
Which? laundry appliance expert Adrian Porter said: ‘Taking apart these machines revealed that the majority of machines made today have sealed drums – where the traditional metal tub has been replaced with a plastic one that has been welded shut – sealing off access to both drum and bearings.
‘If you own one of these machines and the bearings fail, which is one of the top five most common problems with washing machines according to our annual reliability survey, you may have to replace the whole machine as it would uneconomical to repair.
‘None of the machines from the 1980s and 1990s that we dismantled had a sealed drum. On these older machines, the bearings could be accessed and replaced if needed. It seems that washing machine design has changed over time – and not for the better.’
Sealed drums affecting consumers
Which? member Ian Mitchell who wrote to us earlier this year, having experienced this exact problem: ‘I bought a washing machine in 2009. It has been very reliable, but recently the spin cycle has been excessively noisy.
‘The repairer confirmed that the drum bearings had gone. But when he took the top off the machine, the drum (and bearings) were sealed inside a plastic outer tub so they can’t be replaced.
‘The entire drum would need to be replaced, costing more than £200, plus labour. I was his second customer that day, the first customer had an identical problem.
Why design washing machines like this?
Sealed drums are widespread. Almost every manufacturer we investigated make washing machines with sealed drums.
When we questioned manufacturers as to why they make washing machines with sealed drums, most claimed that machines with sealed drums are more reliable.
