Yes they will speaking from personal experience. The granular part of the pod does not fully dissolve and will eventually build up in the sewer pipe.
Tide Pods can cause issues like residue build-up, clogs, or over-sudsing if not used correctly. These problems are more common in older machines or when pods are placed in the detergent drawer instead of the drum. Proper use and regular washer maintenance minimize the risk of damage.
There is some concern about whether dishwasher pods are the best option given the fact that they contain PVA and can have a negative effect on the environment and the plumbing in your home. "It's not necessarily that they aren't the best option, but more so if they can work for you," Novacek says.
Polyvinyl alcohol (PVA) is the film that contains detergent in Tide Pods and other similar products. It dissolves when coming into contact with water, but studies have argued that the process leaves behind microplastics that go on to pollute the water supply, according to the New York Post.
Con: They're usually more expensive than powdered detergent. Con: They have plastic packaging, which is less eco-friendly.
If I'm doing an easy load that doesn't require any extra care, I'll toss in pods. For items that come home dirtier than usual, it's time for a tougher bio detergent probably in pod form. For anything that requires a gentle or handwash cycle, then a liquid detergent customized for silk or wool is a must.
Many dishwashing and laundry detergent pods are coated in polyvinyl alcohol (PVA), which dissolves in water. Gennaro says it is neither safe nor biodegradable as has been claimed. Opt for plastic-free detergent brands and shop at refill stations to reduce your impact.
Many households have turned to using detergent pods because of how convenient they are. Most pods are okay to use if they are marked as “septic-safe.” Be aware that some pods may be damaging for your septic tank if they have elements that don't fully break down, produce too many suds or have high levels of surfactants.
Clear things out by mixing equal parts of hot water and vinegar and pouring the mixture through the drain pipe. Wait half an hour, then reconnect the drain pipe, plug in your machine and run a wash cycle.
For best results, place the pod into the washer drum instead of the detergent drawer. The water temperature isn't hot enough. For pods to dissolve properly, the water temperature in your washer needs to be hot enough.
Place the pac(s) at the back or bottom of the machine drum, not in the dispenser drawer. The number of pacs necessary depends on the load size. To guarantee superior performance, add two Tide PODS® pacs into the washing machine drum before you add clothes.
Cons of Laundry Pods
 Limited Options: Laundry pods do not come in as many different varieties as liquid detergent. This means that if you have specific laundry requirements, such as sensitive skin or allergies, you may have a more difficult time finding a suitable pod.
Are laundry pods bad for your washer? Pods are generally safe for your washing machine, but always check your model's owner's manual. Be sure to take a few precautions as you work them into your laundry routine. Disable any bulk or automatic dispensers in your washer to avoid a double dose of detergent.
Powders can be messy to measure out, whereas capsules and tablets make it really simple to know you're using the correct amount. Gels and liquids usually don't contain any bleach so while they're gentler on clothes, there's more chance of your washing machine getting smelly and needing a regular clean.
