Frequently Asked Questions: Grohe 47598000

Question: Shower can no longer control temperature. Do I have to buy a new spare cartridge assembly?

Answer: The wax thermostat element and/or the shuttle might be causing the problem. This is the link where you can buy the two parts without the housing.

Question: I undid the screw but the handle won’t come off.

Answer: This might be because of sediment calcification. You can try to pull out the handle with extra force. Or you can use WD40.

Question: How to remove a stuck temperature stop ring?

Answer: You can spray WD40 or submerge the cartridge with the stuck stop ring in vinegar for 24 hours. If it won’t come loose it may be time to get a new stop ring.

Question: How will I know if the wax thermostat is broken?

Answer: A wax element gone faulty will have trouble regulating temperature. You can test the capsule by dipping it in cold and hot water. The pin will rise a few millimeters as it is in hot water. You should be able to manually push the pin down after dipping it in cold water. If it does not rise and fall, you need to replace it.
