I recently became the very proud owner of a Creative Vision 5.5. So far, all I've done is patchwork with it. The sound it makes is quite different from my other, older Pfaffs and my DH wonders if it is supposed to sound this way. I don't know how to describe it except to say it sounds kind of 'thunky' if that makes any sense. The question -- is this a normal sound?

pfaff usully purrs--i would hve it checked /check out the sound of the shops machine

Have you tried oiling it and changing the needle? Sometimes that is all it takes.

My Pfaff, which is a 5.0 CV, has a chunky sound to it. As opposed to my Brother which purrs...

Possibly a dull needle? A bit of oil? Hope it is an easy fix!

I have the Pfaff Expression but it purrs!

NO OIL! not necessary. No, no, no.
That's a question I asked my Pfaff dealer (if it ever needed oil). Definitely a NO. Your CV5.5 is all digital. Now, the needle is another thing... I have a Creative 2170, almost 3 yo. It sounds a bit "thunky", but I'd been away from it awhile and maybe I didn't remember it. I changed the needle, no change in the "thunkiness". (It's overdue for it's maintenance.) I was also sewing thru 7-8 layers of fabric, etc. Get it checked, it's free and better to find out now.

my expression 4.0 has a sounds rough too. The dealer said it was because it's bigger than my old pfaff, a classic style quilter, which was smooth. I am not familiar with your machine but Idon't think a bigger, more expensive machine should ride rough. I fell it almost has a shimmey to it. I liked my old phaff alot

It doesn't sew rough, it just has a different sound. I guess I'll call the dealer tomorrow if for no other reason than to satisfy my husband!!

I had a 1471 purchased in 1987 and it was soooo quiet. Now I have a Quilt Expression 4.0 and Creative Vision 5.0. They both have the same sound that you are describing and it is considerably louder than my old one.

I have a 2.0 and mine makes a clunking noise if there is a built up of fluff under the bobbin.
Give it a good clean and see if it is still noisy

Usually when my Pfaff starts sounding a little rough it is either asking for a new needle or the finger on the bobbin is in need of oil. I have a 7550 that is the only place that you oil it.

Try changing the needle, it may have a burr. if it still sounds weird I would take it in for service.

I also have a Pfaff 7550 and it does sound rougher than my Bernina 1530. I have had it checked and nothing is wrong, it just sounds loader than the Bernina.
It is true, you have to keep it clean, keep the hook oiled and change the needle often.

I too love my Pfaff. I would check needle and bobbin. Are you using a good quality thread? It can make a world of difference.

Have the machine checked. I have 2 Pfaffs and they both have sweet sound. If I start hearing a chunky sound I check for lint buildup and/or dull needle. It is possible the needle is slightly bent. Even a new needle can have a bend in it.
