Thetford Aria Dlx II Noise

[elgarc]

Our 12V toilet has begun to sound really loud and "creaky" when it is flushed. Until now (for the last year) it hasn't been so very noisy. Wondering if anyone lubricates their mechanism. If so, what do you use, and how do you do it?

elgarc, we've had our aria 11 for approx 7 yrs now and it's always sounded like a meat grinder.
have repalced 1 motor and a couple of gate seals in the last 6 yrs and finally a complete new mechanism last fall and the new one sounds the same way! no lubrication nessasary according to thetford. i think its the nature of the beast! good luck. jim

Thanx Jim,

Does yours change intensity of the roar? Ours didn't start out this bad, so I'm thinking something has changed...just don't know what it might be. I've written to Thetford by email, so far no response. I'm used to that with some other companies, but if they ever have something to say to me, I'll post back here.

elgarc, the the growl does change from the time the blade starts to open till close. almost funny at times. jim

OK, I am going to take a stab at explaining this....mine did the same thing, ie., "grinding noise got louder"....on the rear of the toilet there is the knob to manually open and close the seal, the shaft runs thru the housing and is attached to the gears inside, there is no replacable bushing in the shaft housing, the housing on mine had worn to the point of excessive shaft play, thus causing the gears to wear uneven and make excessive noise, this will eventually lead to a gear failure, the fix is to replace the motor....Thetford replace mine at no cost...hope this helps.

And holding that knob and its mounting on the rear are several screws. If they get loose the noise will get louder. If they get loose enough, the unit will stop flushing, or jam. You can use a stubby screwdriver and tighten them without removing the toilet.
