Crystal on CrossthwIte Avenue have large machines. Had to use last weekend and they were great, whole place was spotlessly clean and think it was £8 for large one, but I could be wrong as was using small machines too.
The spin doctor was quick to reassure me by text that my dishwasher disaster was really nothing to worry about, and arrived at his first available appointment early, got down to work and all fixed in 20 minutes. This bloke knows his stuff!
