- ① The O-ring repair kit is primarily designed to address issues with leaking hot water or reduced coffee output caused by seal failure in the hot water valve of Philips 4300 and similar coffee machines.
- ② The standard repair kit includes three sizes of O-rings: 50-20 and 90-20 for use in the boiler pin, and 40-40 for use in the brew group.
- ③ The standard repair kit is easy to use and is designed to repair externally accessible O-rings using a hook and tweezers.
- ④ All O-rings are made of food-grade silicone material and applying a small amount of food-grade grease during use will improve sealing performance.
- ⑤ Prior to installation, ensure that the coffee machine is powered off and the water has cooled to avoid the risk of burns or other hazards. Please read the instruction manual and check compatibility before use.
