<br>
We have a customer with a new high efficiency washer running on a Magnum <br>
inverter. When it is in wash cycle, the LED lights flicker rhythmically <br>
with its operation. We can see a corresponding distortion of the wave <br>
form on an oscilloscope, but RMS voltage is steady at 117 vac. It does <br>
not cause trouble with incandescent lighting, and the washer works fine.<br>
<br>
My questions:<br>
<br>
1) Has anyone else seen washing machines causing trouble with lighting <br>
or other loads?<br>
<br>
2) Is there any line filtering available that might cure this?<br>
<br>
3) Are some LED lights more prone to issues? We are considering <br>
having the customer switch from the Home Depot cheapo LEDs to Phillips <br>
or other higher end bulbs.<br>
<br>
4) Could it be related to the bulbs being dimmable? Should we be using <br>
non-dimmable bulbs?<br>
<br>
As always thanks in advance for your invaluable input and comments.<br>
<br>
