What Does the GE Dishwasher H20 Error Mean?

What Does the GE Dishwasher H20 Error Mean?

When your GE dishwasher gets the H20 error code, it signals that something’s up with the water. It’s normally because the dishwasher sometimes needs more water.

This error indicates that the dishwasher is getting less water than it needs to do its job. 

Can I fix it myself? Yes! Most of the time, you don’t need to call an expert. You can fix it yourself by checking a few things.

Following are some reasons why the GE dishwasher might be getting the H20 error:

  • New Dishwasher. If your dishwasher is new, it might display this error at the start. It’s like when you use something for the first time – from time to time, it acts differently until it gets used to things.
  • Need More Water. Sometimes, the dishwasher gets less water than it requires. This is the most probable reason.
  • Water Supply Turned Off. There’s a knob beneath the sink controlling the amount of water going to the dishwasher. If someone turns this off accidentally, the dishwasher might not get water.
  • Hose Problems. The tube carrying water to the dishwasher is probably twisted or blocked by dust.
  • Valve Trouble. There’s a special valve controlling water entering the dishwasher. The dishwasher might only work properly if this valve is fixed or clogged.

How to Fix GE Dishwasher H20 Error?

How to Fix GE Dishwasher H20 Error?

This is how you can fix this error in your dishwasher:

  • New Dishwasher. If your dishwasher is brand new and you’re getting this error, run it a few times, and it should perform normally from then on. 
  • Need More Water. Check if the water pressure is okay. Does the pressure in your faucet match the pressure in your dishwasher? If not, there is a problem with the water mechanism, which needs to be fixed so that the dishwasher receives sufficient water.
  • Water Supply Knob. Look below the sink for a knob. Turn it to make sure water can flow into the dishwasher. This is the water supply for the dishwasher, and it always needs to be on.
  • Damaged Hose. Check the tube, bringing water to the dishwasher. If it’s twisted or bent, straighten it out. A twisted or bent hose can offer resistance to the water flow.
  • Clogged Hose. If gunk or dirt is blocking the hose, clean it out.
  • Different Cycle Option. Try choosing a different washing setting on the dishwasher. Sometimes, switching and then switching back can help.
  • Replacing Valves. If the whole lot else fails, and you suspect the valve is not running right, you may need to switch it out.
