Disassembled, cleaned and lubed 2689W whistle tender. The motor spins like a top now and no longer howls like a banshee, but there is no whistle. Not sure what I did but it's not obvious to me. The impeller seems tight on the shaft, I pulled it off for maintenance. Put a tissue over the impeller inlet to make sure it was ok and the tissue was sucked in when I hit the whistle button on my transformer.
Thanks in advance.
