Noise caused by washer/dryer - How do I get past it?

[saphotoexpress]

Hi, I have a dryer that is causing problems with my device communications.  I've added access points and a 220V plugin filter and still have occasional issues.  If I unplug the dryer, everything works great but the wife is not happy.  I've learned to live with it but thought I would ask the forum if anyone had a simple solution.  Thanks!

Turn off the breaker to the two devices. Simple effective and it works. No need to unplug anything.

Does the dryer have electronic controls?

My thoughts are its electronic controls is generating power line noise or the manufacturer put an AC rated capacitor directly across its power feed and it is a signal sucker.

Was the filter designed for X10 or Insteon signals? Some generic filters will actually kill the X10 or Insteon power line signals as noise.

 

Finding an X10 or Insteon power line filter with a high enough current rating could be a problem. Opening the dryer and just filtering the electronics should work but would void any warranty and maybe have a poor spouse acceptance.

Which filter are you using?

I double checked and it's not a noise filter but a signalinc 220 repeater.  I installed it over a year ago hoping that it would help but it doesn't.  The dryer is plugged into the repeater and then the repeater is plugged into the 220 outlet on the wall.  I'm hoping you guys have a solution because it seems like there should be something better than unplugging or killing the breaker.  Thanks.

I would unplug the repeater and plug the dryer back in and report success / failure.

A SignaLinc repeater (for x10 signals) may interfere with Insteon signalling. If removing the repeater doesn't help, then you can wire-in two X10 XPF filters, one for each opposite leg of the split, single-phase electric supply.

That is an excellent idea for sure. 

 

I am however still wondering if there are other factors at play here. As his title state washer / dryer?

[stusviews]

Good point. Which specific dryer?

I finally got some time to do some testing and I'm thinking that I just have a bad insteon wall switch that needs to be replaced and I probably need to bite the bullet and replace the last of my old x10 devices.  

 

I've got a newer LG clothes dryer and it seems like it is only affecting the x10 devices.  The insteon wall switch gives me a communication error when I launch the admin console and it doesn't matter if the dryer is plugged in or not.   X10 devices don't always respond when the dryer is running and seem to respond better if the dryer is unplugged.  

 

Thanks for the input, I'll replace the x10's and the insteon switch and see how reliable things are after that.

I'm late to the game here, but another possibility are these XPNR wire-in noise suppressors. No amperage limit.  Two would be needed one for each 120 Hot wire, and would hopefully fit in the box with the outlet for the dryer.

 

I have had great success with these from PLM killing interference from a previous furnace, as well as from low voltage lighting transformers. They help X10 and Insteon signals.

 

You are probably looking at around $50 for 2 of them.

Actually only one filter is needed. The filter is rated for 120 or 240 volt devices.
