Problem: Water isn’t hot

Possible Causes

2. Issue with outlet

Solutions

1. Check that the unit is plugged in
2. Check connection at outlet

Problem: Water is too hot or not hot enough

Possible Cause

• Thermostat isn’t correctly adjusted to your setting

Solution

• Slowly adjust the temperature, then turn on the faucet for 5-7 minutes to let it reach temperature

Solutions

Problem: Water comes out of the vent instead of the spout

Possible Cause

• Outlet tube is blocked

Solutions

Problem: Water is dripping from the spout or vent intermittently

Possible Causes

1. Low water pressure in expansion chamber
