Drum Seem
It does look very thin for something that needs to take so much pressure. I would say 'they must know what they're doing' but after this you gotta wonder. On our albeit fairly old Zanussi (2001 ish) the drum seem is almost ribbed, like it's been punched/indented in small sections to reinforce it. I've never seen an Indesit/Hotpoint drum like yours prior to failure so i dunno how strong it looks in comparison, but that rusty strip does look abit feeble.
Definately no harm contacting the various organisations, including Watchdog via their website. The response from Hotpoint/Indesit seems good to me, but what annoys me is that nothing is done until a problem occurs. If it was a car, the manufacturer has to recall even if there's minimal chance of a failure that could compromise safety. Similarly the hammering Beko took from the Authorities/Press when they announced that a batch of older model fridge freezers could catch fire. It seems if you keep hush like Indesit & Candy then it's ok but if you admit a problem (like Beko) then you get punished.
I wouldn't trust a Haier as far as i could chuck them, but Beko washers are alright for the money. I'd have a Beko over most Hotpoint's, though the signs are there that Hotpoint/Indesit have started to turn a corner. It's v difficult to judge todays appliances as the quality can rise & fall from one range to the next - Zanussi dropped dramatically around 2005 when it stopped it's FJS & FLE ranges & moved over to ZWF models, similarly Hoover's quality dropped fast when the Nextra range stopped and Vision HD/Optima ranges started. Hotpoint seemed worst with the WF range (or those of the same age - 2005 ish) but then started to get better again with the latest range looking quite good for the price.
The general rule of thumb seems to be that the least risky brands are (in rough ascending price order) Zanussi, Gorenje, AEG, Bosch, LG, Miele, though AEG doesn't always seem worth the extra money over a Zanussi (same manufacturer, Electrolux) & Bosch is dependant on where it's made (the cheaper stuff isn't always German & can be rubbish).
Hoover/Candy, Haier & Bush seem the ones to avoid, Whirlpool follows not far behind & Hotpoint/Indesit & Beko sit somewhere in the middle, with Hotpoint making less sence than Indesit as they share components but cost more to buy. Beko make sence as a budget choice (upto £250 ish) but i wouldn't spend a fortune on one.
The only thing Beko don't seem to do very well is tumble dryers. All their other stuff seems alright to me. If i was on a budget for a dryer i'd get a cheap Zanussi or a White Knight (made in Britain).
Anyway, i've rambled so i'll shut-up!
