Problem
Everything was working fine for about 3 years. However, recently my LG top-load washer has been occasionally stopping in the middle of a cycle and showing an IE error stating the washer was unable to fill with water.
Findings
Through some trial and error I have consistently been able to get the water flowing again by turning off the the water from the valve on the water hammer arrester and then slowly turning the valve back to the on position and it instantly starts filling with water again.
So is it possible the water hammer arrester is somehow faulty and "freezing up" causing it to block water flow to the washer? But once I relieve pressure by shutting off the valve it resets? Not too familiar with how these devices work.
Stats
- I have checked and cleaned the input filters, they are good.
- Water hammer brand is Ayrlett®
- LG washing machine model: LG WT1201C/WT1101C
- Washer is less than 4 years old
- Apartment is also less than 4 years old
- The hot water input is fine just the cold water one "freezes up"
- I live in a warm environment in an apartment
Best Answer
You might have supply hoses that have an internal shutoff valve in one end which closes if the flow rate is too large. These are designed as protection against a ruptured hose. One brand is Watts FloodSafe(tm) supply hoses.
If you have these, one might be malfunctioning or connected backwards. This type is unidirectional; the end with the control valve must be connected to the water supply. Standard hoses will work no matter which end is connected to the water supply.
I have a set of Watts FloodSafe hoses in a cabinet, but I have not tried to install them on our new "smart" top loader. I had installed them on the washer of an elderly neighbor, but he was dissatisfied with them because his washer was taking too long to fill. I removed them and put in the standard hoses. It is possible that some of the new washers have sensors to detect low flow. Your washer might be detecting low flow and is programmed to shut off and report an error.
