Thanks for the heads up on the AHS dealer. I went ahead and cleaned it again this time. I'm looking for someone familiar with the S130 to take a closer look at things and make any recommendations for other maintenance that I'm skipping over. This will be my 6th season and I've done very little to the boiler other than vacuum, grease, oil and replace the belt.
Do you have a name for the dealer in Washington, NJ?
