GE Washing Machine: water hammer
What is this symptom?
Experiencing loud banging or clanging noises when your GE washing machine fills with water? This water hammer effect occurs due to sudden valve closures in your home plumbing, causing vibrations in the pipes. It's essential to address this issue to prevent potential plumbing damage and ensure a quieter laundry experience.
Important Tips for GE Models
- GE official documentation confirms that rapid closing of washing machine water valves can cause pipe rattling (water hammer) and suggests consulting a professional plumber for root cause resolution.
Possible Causes
Water hammer phenomenon due to sudden valve closure in plumbing
How to Identify: Banging noise immediately after water fill stops; noise in pipes rather than inside drum.
Part: Household water supply lines and washing machine inlet valves
Loose or unsecured pipes in the home plumbing
How to Identify: Movement or vibration of pipework when washer fills or stops; noises reduce when pipes are manually supported.
Part: Water supply lines and pipe brackets
High water pressure or abrupt pressure changes in household plumbing
How to Identify: Banging noise more pronounced with high incoming water pressure; measured household water pressure significantly above normal range.
Part: Water pressure regulator or supply pressure
DIY Solutions
Secure loose water supply pipes
- Locate the water supply pipes feeding the washing machine.
- Check for loose sections that move when the washer actuates.
- Install or tighten pipe clips/straps to secure pipes to nearby studs or framing.
Install washing machine water hammer arrestors
- Turn off the water supply to the washing machine.
- Disconnect the inlet hoses from the shutoff valves.
- Install water hammer arrestors at the shutoff valve outlets.
- Apply Teflon tape to threaded connections for a secure seal.
- Reconnect inlet hoses and restore water supply.
- Test the washing machine to see if noise is reduced.
Adjust household water pressure
- Measure the incoming water pressure with a gauge.
- If pressure is high (above ~60 psi), adjust the pressure regulator to lower the pressure.
- Re-test washing machine to evaluate reduction in noise.
