Hop onto the Cole Parmer website and enter the model number of your pump in the search. It should lead you in the right direction.

Google is your friend! A quick Google search for "77301-22 manual" revealed this:

WOW! It wasn't an encoder issue at all. TLDR: One of the brushes wasn't making contact with the motor, trouble going through the hole.
After letting it sit for a while and let my frustration go away and resist to send it in for "repair" and $$$, I tried to troubleshoot again. So I turned it on, and began turning the motor by hand right before pushing the Play/Start key, and while keep turning it by hand, after I pushed Play/Start key the RPM would actually readout the number for a second or two before going to Error 1. That gave me hope that it wasn't an encoder issue at all. So I opened the motor back up and troubleshoot the motor itself. I looked this video up real quick "How to troubleshoot brushed DC motor" https://www.youtube.com/watch?v=sWEsPw733h8
I put my multimeter on the positive and negative leads and got nothing. Tried the 9v battery and nothing. I took a closer look and ended up being one of the brushes wasn't fitting through the hole properly and no contact to the motor. After I verified both brushes making contact again, the multimeter was reading some resistance and the 9v battery made the motor run. All is good, no encoder issue, and save me some $$$.

Some heads will click a bit due to play in the housing and or rollers. If the head doesn't click when there is no tubing in it, that is likely the reason and you probably don't need to worry.

I know it's in the thread somewhere but can someone please tell me how often tubing is supposed to be replaced?

I do it quarterly but you can go half a year or more. It's cheap though so imo it's better safe than sorry.

Ecotech continuous duty dosing pumps are on the horizon. Finally a company has answered our needs in a dosing pump durable enough for our use. I’ll do my best to get one as soon as possible to run it through the gauntlet!

I have a new to me Masterflex 77301-22. Last night my power went out for a few minutes, when I got up in the morning and checked my tank the unit's power was on but was not running, I had to restart it. Is this the norm for these units, every time my power goes out I have to restart it, or am I missing something.

Looking forward to joining the #MasterFlexGang . With the help from [MENTION=225253]slief[/MENTION] I was able to procure a killer deal on a Cole-Parmer MasterFlex L/S Peristaltic Pump 7523-80 with a Cole-Parmer - EW-77800-62 - Masterflex L/S Easy-Load 3 Head.
They want you to run LS/17 tubing with this head, so that I what I purchased. I know most are running LS/15, but I assume this won't be an issue.
I also had [MENTION=296993]alanle[/MENTION] build a custom Dual Stage Regulator for me with the following parts.
-Stainless steel dual stage GO regulator (rebranded from Swagelok)
-Clippard .07 volt solenoid
-Swagelok ultra fine Needle valve
-Swagelok liquid gauges
It will be running my CoralVue CR5000D reactor. I will also run a Milwaukee MC122 pH Controller with my Apex as backup should something fail.
I hope to be able to keep my pH more constant/stable within a much less degree of swing.
This is the first time I have ever used a Pera pump to run a reactor, I have always been bubble chaser and effluent chaser, so this will be a nice change of pace!

According to the specs, that head is not compatible with LS17 tubing so you might wear the tubing out faster or potentially damage the head. I would contact cole parmer support and ask them what the ramifications are when running LS17 tubing with that EW-77800-62 head as the tubing diameter and or wall thickness is different than the others listed for compatibility.

My apologies, I bought Masterflex L/S C-Flex Tubing 50 A, L/S 15, 25 ft. That was the tubing if I ended up buying a new head... I ended up keeping the head that came with it, that was if I were to replace it.
Only downside to the LS15 is it's low flow rate per RPM. You will be running the motor at a higher speed than if you were using LS24 which is similar to LS17 flow rates or LS35 or 36 which have even high flow rates which means even lower RPM on the motor and less wear and tear.

I will pickup some LS24 to play with.
