<p>No error codes, just light flickering with the washing action.
Its a Magnum MS 4448 PAE, 48 v 845 AH of HUP batteries, 2/0
cables. Happens day or night. Also the lights are not on a
dimmer, just a regular switch. It happens to the LEDs all over
the house. They are the Econolight brand from Home Depot. Feit
brand have less flicker, but are still not acceptable.</p>
<p>We're thinking the distortion of the waveform by the washer is
creating harmonic distortion that the LEDs are responding to.
Still hoping filtering or different bulbs will fix the issue. <br>

Esteemed Wrenches;<br>
<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>
