Hi Liam, I think the WK condensers are ok, but if I was to choose between that and a Zanussi, then a Zanussi every time. Although if the choice was between Hoover / Candy, or Indesit, then a White Knight over those.
Yes ice can be used with water in the trap, it will help keep the water cooler for longer. So better get on eBay for an ice machine for the house warming and for the dryer lol.
Those little Philips based dryers can also be found branded as Zanussi, Bendix, Carlton, hope that widens your search Tom =)
