Frequently Asked Questions: Wax Thermostat Element for Grohe 00798000

Question: How can I take out the element?
Answer: Taking the element out is contingent on the type of cartridge and shower you own. Some cartridges require the removal of the slider latched onto the bottom of the cartridge housing. For other cartridges; spring, seals, and washers need to be removed before you can get to the wax thermostatic element.

Question: Can I know if the capsule needs a replacement?
Answer: You can test the Grohe 00798000 capsule element by dipping it in hot and cold water. If the pin does not move up and cannot be pushed down with ease, you need to replace the part.

Question: Why is the shower not producing hot water?
Answer: Issues from the supply pipes or from the valve unit components may lead to sluggish hot water flow from the bathtub or shower tap. If supply pipe pressure is lacking adjust it. If the temperature limiter is misaligned, readjust it. However, if there are no troubles with water pressure or part installation, the cartridge should be checked.

Reasons for a lack of hot water that does not originate from the supply lines or valve installation include a faulty Grohe 00798000 thermo-element.

Question: What contributes to a faulty wax element?
Answer: High levels of hard water will not only affect the cartridge barrel or the tap unit, but also the temperature sensitive Grohe 00798000 capsules inside the cartridge. White and rust coloured deposits found on shower enclosures and appliances are signs of hard water presence.

Hard water minerals will react more when the temperature is high. Because of this, debris will build up on the pathway where hot water passes – gauzing and thermostat element. The development of debris can hinder the normal functioning of the little temperature regulators.

Living in an area where hard water levels are high?
- We have a Magnetic Limescale Inhibitor. It is a natural solution for limescale buildup.
