Did the job - excellent
Although the old washers looked fine, they just didn't seal the water inlet chamber of my bosch dishwasher. New washers did the job though. Very happy. Note, push the washer to the bottom of the aperture in which they sit, then push the chamber male part through. (Dont put the washer on the male part first)

Perfect fit but way too expensive.
Fits to the side entry flow / drain trap, easy to fit. Very expensive for 4 o rings

Great product = stopped leak
When fixing our dishwasher I needed to replace these washers and Ransom Spares came up trumps. My only issue was the price and particularly p&p since the items fitted in a 1st class envelope. Have used Ransom Spares before and will do again

Easy to fit
Our dishwasher had issues with filling and after removing the labyrinth and giving it a darn good clean with white vinegar, all seemed well. However, the O rings, having been disturbed, no longer formed a perfect seal so new ones were required. These were just what I needed and came in good time. I am very happy with the service and quality from Ransom. I will use them again.

East to Fit
Thanks to the team at Ransomspares for confirming these were the correct washers very quickly. Washers very easy to fit, the hardest job, especially for an integrated dishwasher is removing it to access the water distribution array. Used a silicon spray as a lubricant to ensure fit was secure as tight fit required. Sounds expensive for 4 washers, but resolved what could have been a very expensive repair or even a replacement dishwasher.
