Following on from the discussion here recently, on a whim, I noticed that ASDA sell plain own-brand dishwasher tablets at £1.50 for 30 (5p each).
Been using them all weekend, and buggered if I can see any difference between them and the ultimate squidgy ones with lemon scent we were using (at c. 11p a tablet).
So that's that sorted.
Now the instructions say *not* to put in the cutlery tray, but I ignored that because our flippy dispenser packed up years ago (it was advice here that meant I didn't bother replacing it).
On a whim I googled a bit, and noticed that while the specific part for a Hotpoint SDD910 is quite pricey, there are what look to be identical spares on eBay for an Indesit machine.
Anyone here know if they are likely to be the same. So far the seller hasn't responded to me, but at £20 rather than £60+, it's tempting.
