WATER WILL NOT FLOW - GE Profile 25.6 Cu. Ft. Side-by-Side Refrigerator with Thru-the-Door Ice and Water - Stainless-Steel

There are a few other potential causes for slow water flow in a washing machine:

1. Clogged or partially clogged water inlet valve: The water inlet valve is responsible for controlling the flow of water into the washing machine. If it is clogged or partially clogged, it can cause a reduction in water flow.
2. Washing machine pump: The pump is responsible for moving water through the washing machine. If it is damaged or not functioning properly, it can cause a reduction in water flow.
3. Water supply hose: The hose that supplies water to the washing machine may be clogged or damaged, which could cause a reduction in water flow.
4. The washing machine itself: There could be an issue with the internal components of the washing machine that is causing the slow water flow.

If you have checked the filters, water pressure, and solenoid and they are all functioning properly, you may want to try checking the water inlet valve, pump, water supply hose, and the washing machine itself for any issues that could be causing the slow water flow.

Flo ? for Flow Error?

That would for any number of reasons that the Flow Switch is not sensing enough water flow to trip the sensor/pressure switch or actual true water flow switch.

Heater will not run or heat, if there is not enough water flowing!
The heater will sense this. So, whatever will restrict or stop sufficient water flow is the problem.

• Dirty filter
• Closed valves
• Not enough water in tub or pool - low water level
• Clogged pump impeller
• Clogged baskets:
  • at pump or at skimmers
• Clog / stopped up plumbing line

And finally, you may have a bad flow switch/sensor

The low flow message on any Balboa means that you are having an issue with the flow of water through your heating unit. This can be caused by a few things.

• Low water levels
• Dirty filters
• Something is impeding your water flow

Top up your water level and make sure it is where it needs to be, clean your filters or replace them, and check that nothing is impeding your water flow at the skimmer or water intakes.

F2 Error Code Trouble Shooting

Hi and welcome to FixYa, I am Kelly.

What is happening is that your cold water flow is greater in volume (gals per min) than your hot water. So when you open the cold water it is mixing with the hot water inside the faucett or shower plumbing and actually reverse flowing back into the hot water heater plumbing. The reverse flow slows the water flow sensing turbine inside the heater and it is thinking that there is not any water flow. (There isn't actually due to the equalization of water pressure when you open the cold water faucett) Since this is a safety feature of the tankless heater to keep it from overheating, it shuts off.
Somewhere in the hot water plumbing there is a major restriction. It may very well be the internal plumbing of the tankless hot water heater or the flow detector design.

There are 2 ways to correct this. The easy way would be to restrict the available cold water flow. You can do this by installing another shut off valve inline with the cold water plumbing and just not open the valve all the way. You would have to adjust the setting so that the hot and cold water can be on at the same time and the hot water heater stays on. The hard way is to locate the hot water flow restriction and eliminate it.
It is possible.... if you have a flow restrictor in a shower head or a screen in a faucett areator that they are partially clogged. Clean any flow restrictors and screens then see how the hot water heater performs before you start modifying plumbing.

There is a minimum water flow required to operate your Bosch tank-less water heater. It is around .75 gallons a minute. There are three things you can do to help the flow.
1.Turning the temperature down will help increase the flow.
2. Installing higher flow aerators on your faucets.
3. Clean the Bosch tank less water heater.
You are not alone in having this issue. The most common problems are low flow faucet aerators and low flow shower heads.

If it's a new install: the water is going backwards through the heater and you need to check that your cold water IN is actually hooked up to the cold water IN spot on the heater. they don't register flow if the flow goes backwards through the heater.
If it's not a new install: something is stuck in your flow sensor, drain the unit and take it out to check.

you probably had debris get into the filter or flow sensor when the water was turned back on. I'd recommend checking the filter first and if that doesn't work, call Noritz Tech support to help you with the flow sensor.

the filter is a black plug located on the cold water line (labeled cold on the bottom of the unit). It points torwards the left.

It might be a question of inadequate flow. All tankless water heaters have a minimum flow rate that must be met, typically .5-.9 gpm, before the heater will operate. In the summer time the incoming ground water temperature is higher, causing you to mix more cold water and less hot water to get a lukewarm temperature. This can reduce your flow rate near or below the minimum flow rate.
Here's a test for you, try running running a sink while taking your next shower. If the hot water remains mostly constant throughout, then your problem is with flow at the showerhead. The flow at a shower head can be reduced by buildup of scale and sediment. Also all showerheads have a flow restrictor that limits flow to 2.5gpm (some even less). Removing the restrictor will increase the showerhead flow rate as well.
Also look for any error code displayed on the digital read out of the heater. Some heaters will flash on their burner indicate light as well.
