designez 0 Report post Posted February 7, 2013 Our Alpha Smart 18E Instant Water Heater stopped working last week after only 1,5 years and the water pressure was getting low. We called Alpha Service (67478300) and a friendly local repair uncle came by. Fortunately no electrical parts were broken, just the water filter was clogged! The Alpha 18E has a safety feature so it does not turn on when the water pressure is too low.After he cleaned the filters everything worked fine and water pressure was powerful again Share this post Link to post Share on other sites
