Found Tankless Water Heater In Fault Status, Flashing 2 Codes E010 (Abnormal Air Pressure) And E027 (Abnormal Activity Of Air Pressure). Checked Intake Filter And It Was Clogged With Dirt And Dust. Cleaned Off Filter And Put Cover Back On Unit. Ran For 15-20 Minutes On High Heat For First Level. Found Temps Ranging From 110-115. Tested System Again After Putting Back Filter, Controller Does Not Fully Sense Flow Of Water When Using Kitchen Sink, This May Be Due To The Low Water Pressure, However The Sink Was Receiving 110 So It Is To Be Assumed That The Tankless Is Just Producing Minimal Amount Of Heat Required To Run One Faucet. *Note* If This Does Stem Into An Issue With The Production Of Hot Water For A Single Faucet And The Unit Does Not Run While Calling For Hot Water, Then It May Be Assumed That The Flow Sensor In The Tankless Water Heater May Be Clogged And Need Replacing. System Is Fully Operational Right Now.

CM Heating Performed Maintenance On Tankless Hot Water Tank. Customer Has A Concern With Error Code 10 Being Activated Intermittently. I’ve Check And Confirm There Is Not Air Flow/exhaust Restriction. I’ve Made One Configuration Setting To The Control Board Which Should Match The Venting Length According To The Physical Primeters Specification According To The Manufacturers Data. If This Does Not Solve The Issue, Then The System May Need Replacing Since There Is A History Of Attempted Repairs But No Solid Solution. There May Be A Factory Defective Part That Is Not Serviceable.

Customer's Tankless System Is Not Working Properly And They Currently Are Without Hot Water. It Was Difficult To Understand The Customer, But Sounds Like She Has Been In Contact With Rannai And They Referred Her To Us. She Mentioned Having The Builder Pay For This Visit But I Explained That Payment Was Required At Time Of Visit. She Said She Would Write A Check And Worry About Reimbursement From The Construction Company. Please Try To Diagnosis. She Provided Her Rannai Case Number #303493 And Said That Rannai Determined That The Issue Was Due To Installation, Not The Equipment. Upon Investigation, The Technician Found That The Tankless System Was Displaying An Error Code 19, Which Indicates A Grounding Fault. Unit Has A Loose Or Shorted Wire That Can Not Be Located At This Time Due To The Problem Being Resolved While Double Checking All Connections. Problem Is/was In One Of The Connections But Was Never Specifically Located. System Is Currently In Good/proper Working Order But Issue May Or May Not Happen Again. If So Further Diagnosis On The Factory Wire Connections Should Be Performed.
